[PATCH] selinux-testsuite: don't break the system after running the cgroups_label tests

[Paul Moore <paul@xxxxxxxxxxxxxx>]

From: Paul Moore <paul@xxxxxxxxxxxxxx>

Commit be0ca8feeb9b ("selinux-testsuite: ensure the cgroups_label
tests works on old and new systems"), and perhaps an earlier related
commit, broke systems after the tests were run by operating on
/sys/fs/cgroup/unified directly and not a sub-directory.  Fix this
by restoring the old (sub-directory) behavior.
