Subject: When use stat -c %D instead of stat -f -c %i for testing if /new_root
 is a mount point

The old check couldn't distinguish different tmpfs mounts and failed to work with aufs (archiso).
This check is actually the same one that busybox/switch_root uses to determine where
to stop deleting files. If this check fails and we still launch switch_root it may start
deleting data.
