Kir Kolyshkin 5cdf76719e libct/cg: IsCgroup2UnifiedMode: don't panic ...

Replace a panic with a warning, unless it's ENOENT and we're running in
a user namespace. In the latter case, do the same as before, i.e. report
the error but using a Debug logging level.

This prevents software that uses libcontainer from panicking in
some exotic setups.

This will also print a warning on some very old systems which does not
use /sys/fs/cgroup for cgroup mount point. My bet is such systems no
longer exist.
