Since we're not not mounting anything but the base filesystem outside
the container we no longer need the separate bind mount at
/var/lib/docker/container/$id/root in order to see the base filesystem
without extra mounts. So, we drop this and mount (again) the container
root directly at the real basefs mountpoint.
