subsystemsUnified is used on a system running with cgroups v2 unified
mode.

Transient units (and transient slice units) have been available for quite a
long time and RHEL 7 with systemd v219 (likely the oldest OS we care about at
this point) supports that. A system running a systemd without these features is
likely to break a lot of other stuff that runc/libcontainer care about.
Regarding delegated slices, modern systemd doesn't allow it and
runc/libcontainer run fine on it, so we might as well just stop requesting it
on older versions of systemd which allowed it. (Those versions never really
changed behavior significantly when that option was passed anyways.)

This removes "github.com/coreos/go-systemd/util", no longer needed after
removing the dependency on it.
It also gets rid of "github.com/coreos/pkg/dlopen", since that was only
referred to by the aforementioned "util" package.
Tested that everything builds and works as expected.

This dependency is only needed in package "github.com/coreos/go-systemd/util"
and we only use it for IsRunningSystemd(), which is a simple Go function that
just stats a file.
Let's just borrow it here, so we remove the dependency and can remove that
package from vendored build.
This also removes dependencies on dlopen and on trying to find libsystemd.so
or libsystemd-login.so in the system.
Tested that this still builds and works as expected.

The man-pages are using pre-formatted section to display the options for
all commands. The result on my system never looked correct:
OPTIONS
--bundle value, -b value path to the root [...]
--console-socket value path to an AF_UNIX [...]
The first line was always indented less than the other lines.
This commit makes the option block a pre-formatted block (as intended???) by
using 4 spaces instead of 3 spaces.
In addition the man-pages did not specify their name and section
correctly. This adds something like '% runc-run "8"' to all man-pages to
have correct title 'runc-run(8)' instead of 'NAME()' and it also adds
the section to the title: 'System Manager's Manual'.
This also fixes the use of '>' and '<' at multiple places. The markdown
source files were using "<container-id>" and similar which was (most of
the time) rendered as '""'. On some systems it was rendered correctly.

`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.

when exec as root and config.Cwd is not owned by root, exec will fail
because root doesn't have the caps.
So, Chdir should be done before setting the caps.

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.
