`Init` on the `Process` struct specifies whether the process is the first process in the container. This needs to be set to `true` when running the container.

Currently, the id verification in integration test failed on arm
platform due to the inconsistent /etc/group in the busybox images
for arm and x86. To be specific, the nogroup id in x86 is 99 while
that in arm is 65534.
99 is old id for nogroup, and no longer be used in recent system,
so sync the busybox image for arm and x86 to the image in busybox
github. Also change the id verification rule in integration test.

Some package managers download the archive instead of cloning the git repo.
When they do that, the call to git fails.
This commit allows package managers to provide the COMMIT value via environment.

The hugetlb cgroup control files (introduced here in 2012:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=abb8206cb0773)
use "KB" and not "kB"
(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/mm/hugetlb_cgroup.c?h=v5.0#n349).
The behavior in the kernel has not changed since the introduction, and
the current code using "kB" will therefore fail on devices with small
amounts of ram (see
https://github.com/kubernetes/kubernetes/issues/77169) running a kernel
with config flag CONFIG_HUGETLBFS=y
As seen from the code in "mem_fmt" inside hugetlb_cgroup.c, only "KB",
"MB" and "GB" are used, so the others may be removed as well.
Here is a real world example of the files inside the
"/sys/kernel/mm/hugepages/" directory:
- "hugepages-64kB"
- "hugepages-2048kB"
- "hugepages-32768kB"
- "hugepages-1048576kB"
And the corresponding cgroup files:
- "hugetlb.64KB._____"
- "hugetlb.2MB._____"
- "hugetlb.32MB._____"
- "hugetlb.1GB._____"

This will permit us to extend the internals of systemd.Manager to include
further information about the system, such as whether cgroupv1, cgroupv2 or
both are in effect.
Furthermore, it allows a future refactor of moving more of UseSystemd() code
into the factory initialization function.

We discovered in umoci that setting a dummy type of "none" would result
in file-based bind-mounts no longer working properly, which is caused by
a restriction for when specconv will change the device type to "bind" to
work around rootfs_linux.go's ... issues.
However, bind-mounts don't have a type (and Linux will ignore any type
specifier you give it) because the type is copied from the source of the
bind-mount. So we should always overwrite it to avoid user confusion.

Add support for children processes logging (including nsexec).
A pipe is used to send logs from children to parent in JSON.
The JSON format used is the same used by logrus JSON formatted,
i.e. children process can use standard logrus APIs.
