selftests/filesystems: test that a mntns file can't take over a lock
Add a case to the locked mount test:
- a bind of the mount namespace file of a grandchild moved beneath a
locked cover must fail with EINVAL
- a bind of an ordinary file beneath it takes the lock over, the old
cover can go and the new one can't
- the file is still covered after unshare(CLONE_NEWNS)
