ABAT: handle even obscurer SLES root specifier

It seems that in SLES images root will be shown mounted on /dev/root
but that /dev/root will not even exist.  At this point we have use
the mtab to determine where / is mounted from.  Use df -lP to find
the underlying device for passing to the boot loader.
