Dropping unionfs-fuse support:

  * unionfs-fuse itself has been always very buggy for us.
  * unionfs-fuse code in live-boot as been experimental at best.
  * the FUSE implementation is horribly slow due to the nature of
    FUSE (~10min to boot a live system with unionfs-fuse compared
    to <<1min with aufs).
  * and last but not least, there's overlay in kernel mainline now.
