For cgroup v1, run a process in the child cgroup during
the recursive cgdelete tests - 002-cgdelete-recursive_delete.py.
In cgroup v1, cgdelete should migrate the process to its
parent cgroup.
If the test is being run on a cgroup v2 system, don't
create the process. Cgroup v2 doesn't support processes
running in a non-leaf cgroup, so cgdelete's recursive
command doesn't really make sense.
