Make better use of UUIDs on Intel platform wks files

- Stop using --ondisk XXX in the wks files, that enforces using
  USB/SATA/etc as /etc/fstab will be referencing these devices.
- Pass --use-uuid for the boot partition
- Update mkefi-agl.sh and mkabl-agl.sh to modify the final fstab to
  use the PARTUUID they create rather than the PARTUUID of the resulting
  wic file.
