Ed Santiago 1646da834c System test additions
- run --userns=keep-id: confirm that $HOME gets set (#8013)

 - inspect: confirm that JSON output is a sane number of
   lines (10 or more), not an unreadable one-liner (#8011
   and #8021). Do so with image, pod, network, volume
   because the code paths might be different.

 - cgroups: confirm that 'run' preserves cgroup manager (#7970)

 - sdnotify: reenable tests, and hope CI doesn't hang. This
   test was disabled on August 18 because CI jobs were hanging
   and timing out. My suspicion was that it was #7316, which
   in turn seems to have hinged on conmon #182. The latter
   was merged on Sep 16, so let's cross our fingers and see
   what happens.

Also: remove inaccurate warning from a networking test.

And, wow, fix is_cgroupsv2(), it has never actually worked.
