selftests/filesystems: check that a copied mount namespace keeps unbindable
Make a tmpfs unbindable, copy the mount namespace and check from the
copy that:
- a bind of the mount fails with EINVAL
- a recursive bind fails as well
- open_tree(OPEN_TREE_CLONE) of it fails
- mountinfo still shows it as unbindable
- a copy of the copy refuses the bind too
The first case runs in the original namespace so the fixture stays
honest about what it set up.
