[PATCH 1/2] selftests/cgroup: fix missing TAP output in test_hugetlb_memcg

main() in test_hugetlb_memcg never calls ksft_print_header(),
ksft_set_plan(), or ksft_finished(), so its output has no TAP plan and is
not valid TAP, unlike the sibling test_memcontrol and test_kmem tests.
Add the header/plan/finished calls following the same pattern.
