ftests: skip test 002 on legacy, containerized test runs

Skip test 002-cgdelete-recursive_delete.py on legacy (cgroup v1),
containerized test runs.  It occasionally fails in Github Actions, and
I think the failure is simply because the machine is underpowered.  In
these cases, the failure is usually reported as:
	002-cgdelete-recursive_delete.py - Failed to get the pid of the child process:
