units: add umount unit files for Debian

Add unit files to call

/etc/init.d/umountnfs.sh stop (network file systems)
/etc/init.d/umountfs stop     (local file systems)
/etc/init.d/umountroot stop   ("/" file system)

in the right order and hook them up in the umount.target so they are run
on shutdown and reboot.
