Move the deletion of unnecessary systemd units and files from
image_builder.sh into rootfs.sh.
The files being deleted can be applicable to other image file formats
too, not just to the rootfs-image format created by image_builder.sh.
Also, image_builder.sh was deleting these files *after* it calculated
the size of the rootfs files, thus missing out on the opportunity to
possibly create a smaller image file.

The 'part_start' of image and dax_image should exactly specify the
same location, according to the parted documentation, to exactly
specify the location, the units of start and end should use MiB.

Remove the `chcon` operation which adds `container_runtime_exec_t` label to
the `kata-agent` binary because the container-selinux package including
the 39f83cc74d
commit has been released officially.
Ref. https://centos.pkgs.org/9-stream/centos-appstream-x86_64/container-selinux-2.221.0-1.el9.noarch.rpm.html
The container-selinux package is installed in a guest rootfs when we create it with `SELinux = yes`,
and `restorecon` sets `container_runtime_exec_t` to the `kata-agent`.

It's too long a time to cross build agent based on docker buildx, thus
we cross build rootfs based on a container with cross compile toolchain
of gcc and rust with musl libc. Then we get fast build just like native
build.
rootfs initrd cross build is disabled as no cross compile tolchain for
rust with musl lib if found for alpine and based on docker buildx takes
too long a time.

partition as hash device to save hash data of rootfs data blocks.

For kata containers, rootfs is used in the read-only way.
EROFS can noticably decrease metadata overhead.
On the basis of supporting the EROFS file system, it supports using the config parameter to switch the file system used by rootfs.

Create a guest image to support SELinux for containers inside the guest
if `SELINUX=yes` is specified. This works only if the guest rootfs is
CentOS and the init service is systemd, not the agent init. To enable
labeling the guest image on the host, selinuxfs must be mounted on the
host. The kata-agent will be labeled as `container_runtime_exec_t` type.

This patch fixes inconsistent calculations of the rootfs size.
For `du` and `df`, `-B 1MB` is different from `-BM`. The
former is the power of 1000, and the latter is the power of
1024. So comparing them doesn't make sense. The bug may result
in a larger image than needed.

There is an inconformity between qemu and kernel of memory alignment
check in memory hotplug. Both of qemu and kernel will do the start
address alignment check in memory hotplug. But it's 2M in qemu
while 128M in kernel. It leads to an issue when memory hotplug.
Currently, the kata image is a nvdimm device, which will plug into the VM as
a dimm. If another dimm is pluged, it will reside on top of that nvdimm.
So, the start address of the second dimm may not pass the alginment
check in kernel if the nvdimm size doesn't align with 128M.
There are 3 ways to address this issue I think:
1. fix the alignment size in kernel according to qemu. I think people
in linux kernel community will not accept it.
2. do alignment check in qemu and force the start address of hotplug
in alignment with 128M, which means there maybe holes between memory blocks.
3. obey the rule in user end, which means fix it in kata.
I think the second one is the best, but I can't do that for some reason.
Thus, the last one is the choice here.
