Zbigniew Jędrzejewski-Szmek 8328d8c633 test-cgroup-mask: fix masks in test and enable by default
Commit 637f421e5c ("cgroups: always propagate controller membership
to siblings") changed the mask propagation logic, but the test wasn't
updated.

Move to normal tests from manual tests, it should not touch the system
anymore.
