selftests/filesystems: test OPEN_TREE_DROP_MNTNS_MOUNTS
Pin a mount namespace below a tmpfs mount, the way snapd does under
/run/snapd/ns, and attach a recursive clone of that tmpfs inside a
younger mount namespace created with OPEN_TREE_NAMESPACE. Without
OPEN_TREE_DROP_MNTNS_MOUNTS move_mount(2) fails with ELOOP; with it,
it succeeds.
Also check that the flag is rejected without OPEN_TREE_CLONE or
OPEN_TREE_NAMESPACE, and accepted with the latter.
