NOT_IF_ROOT and MNT_REMOUNT are both confusing since they both can mean
different things (root as uid 0 or root of fs, remount as in -o remount).
Simply do not allow mounting the same filesystem twice on the same
mountpoint. Mounting _another_ filesystem on an existing mountpoint
should not be prohibited as that is needed for union mounts.
