selftests/bpf: test_progs: add test__join_cgroup helper test__join_cgroup() combines the following operations that usually go hand in hand and returns cgroup fd: * setup cgroup environment (make sure cgroupfs is mounted) * mkdir cgroup * join cgroup It also marks a test as a "cgroup cleanup needed" and removes cgroup state after the test is done.
