Added variable REPO_COMPONENTS (default: "main") which sets components
used by mmdebstrap for rootfs building.
This is useful for custom image builders who want to include EXTRA_PKGS
from components other than the default "main" (e.g. "universe").

This exposes REPO_URL and adds REPO_URL_X86_64 which can be set to use
custom Ubuntu repo for building rootfs.
If only one architecture is built, REPO_URL can be set. Otherwise,
REPO_URL_X86_64 is used for x86_64 arch and REPO_URL for others.

The previous attempt to fix this issue only took in consideration the
QEMU binary, as I completely forgot that there were other pieces of the
config that we also adjusted.
Now, let's just check one of the configs before trying to adjust
anything else, and only do the changes if the suffix added with the
multi-install suffix is not yet added.{

Linux CoCo x86 guest is hardened to ensure RDRAND provides enough
entropy to initialize Linux RNG. A failure will panic the guest.
For confidential guests any other RNG source is untrusted so disable

As the comment in the fragment suggests, this is for the firecracker builds
and not relevant for confidential guests, for example.
Exlude mmio.conf fragment by adding the new !confidential tag to drop
virtio MMIO transport for the confidential guest kernel (as virtio PCI is
enough for the use cases today).

build-kernel.sh supports exluding fragments from the common base
set based on the kernel target architecture.
However, there are also cases where the base set must be stripped
down for other reason. For example, confidential guest builds want to
exclude some drivers the untrusted host may try to add devices (e.g.,
virtio-rng).
Make build-kernel.sh to skip fragments tagged using '!confidential'
when confidential guest kernels are built.

Once the multiInstallSuffix has been taken into account, we should not
keep appending it on every re-run/restart, as that would lead to a path
that does not exist.

Knowing that the upstream project provides a "ready to use" version of
the kernel, it's good to include an easy way to users to monitor
performance, and that's what we're doing by enabling the TASKSTATS (and
related) kernel configs.
This has been present as part of older kernels, but I couldn't
reasonably find the reason why it's been dropped.

Kata Containers provides, since forever, a way to run OCI guest-hooks
from the rootfs, as long as the files are dropped in a specific location
defined in the configuration.toml.
However, so far, it's been up to the ones using it to hack the generated
image in order to add those guest hooks, which is far from handy.
Let's add a way for the ones interested on this feature to just drop a
tarball file under the same known build directory, spcificy an env var,
and let the guest hooks be installed during the rootfs build.
