Enable seccomp support in `runk` by default.
Due to this, `runk` is built with `gnu libc` by default
because the building `runk` with statically linked the `libseccomp`
and `musl` requires additional configurations.
Also, general container runtimes are built with `gnu libc` as
dynamically linked binaries by default.
The user can disable seccomp by `make SECCOMP=no`.

"inline-virtio-fs" is newly supported by kata 3.0 as a "shared_fs" type,
it should be described in configuration file.
"inline-virtio-fs" is the same as "virtio-fs", but it is running in
the same process of shim, does not need an external virtiofsd process.

Kata 3.0 introduced 3 new configurations under runtime section:
name="virt_container"
hypervisor_name="dragonball"
agent_name="kata"
Blank values will lead to starting to fail.
Adding default values will make user easy to migrate to kata 3.0.

Refactor the container builder code (`InitContainer` and `ActivatedContainer`)
to make it easier to understand and to maintain.
The details:
1. Separate the existing `builder.rs` into an `init_builder.rs` and
`activated_builder.rs` to make them easy to read and maintain.
2. Move the `create_linux_container` function from the `builder.rs` to
`container.rs` because it is shared by the both files.
3. Some validation functions such as `validate_spec` from `builder.rs`
to `utils.rs` because they will be also used by other components as
utilities in the future.

In the commit 54d6d01754 we ended up
removing the BUILD_SUFFIX argument passed to QEMU as it only seemed to
be used to generate the HYPERVISOR_NAME and PKGVERSION, which were added
as arguments to the dockerfile.
However, it turns out BUILD_SUFFIX is used by the `qemu-build-post.sh`
script, so it can rename the QEMU binary accordingly.
Let's just bring it back.

Following the instructions in guidance doc will result in the ECONNREFUSED,
thus we need to keep the unix socket address in the two commands consistent.

Dockerfile cannot decipher multiple conditional statements in the main RUN call.
Cannot segregate statements in Dockerfile with '{}' braces without wrapping entire statement in 'bash -c' statement.
Dockerfile does not support setting variables by bash command.
Must set HYPERVISOR_NAME and PKGVERSION from parent script: build-base-qemu.sh

amend_spec do two works:
- modify the spec
- check if the pid namespace is enabled
This make it confusable. So split it into two functions.

Augment the mock hypervisor so that we can validate that ACPI memory hotplug
is carried out as expected.
We'll augment the number of memory slots in the hypervisor config each
time the memory of the hypervisor is changed. In this way we can ensure
that large memory hotplugs are broken up into appropriately sized
pieces in the unit test.

If we're using ACPI hotplug for memory, there's a limitation on the
amount of memory which can be hotplugged at a single time.
During hotplug, we'll allocate memory for the memmap for each page,
resulting in a 64 byte per 4KiB page allocation. As an example, hotplugging 12GiB
of memory requires ~192 MiB of *free* memory, which is about the limit
we should expect for an idle 256 MiB guest (conservative heuristic of 75%
of provided memory).
From experimentation, at pod creation time we can reliably add 48 times
what is provided to the guest. (a factor of 48 results in using 75% of
provided memory for hotplug). Using prior example of a guest with 256Mi
RAM, 256 Mi * 48 = 12 Gi; 12GiB is upper end of what we should expect
can be hotplugged successfully into the guest.
Note: It isn't expected that we'll need to hotplug large amounts of RAM
after workloads have already started -- container additions are expected
to occur first in pod lifecycle. Based on this, we expect that provided
memory should be freely available for hotplug.
If virtio-mem is being utilized, there isn't such a limitation - we can
hotplug the max allowed memory at a single time.

00aadfe20a introduced a regression on
`make cc-tdx-kernel-tarball` as we stopped passing all the needed
information to the `build-kernel.sh` script, leading to requiring `yq`
installed in the container used to build the kernel.
This commit partially reverts the faulty one, rewritting it in a way the
old behaviour is brought back, without changing the behaviour that was
added by the faulty commit.
