[iso] fix GRUB boot for newer Arch and derivatives

Browse source 
* Arch recently added a "search --no-floppy --set=root --label <LABEL>" into their
  grub.cfg, which we didn't have provision for patching, which means that, as soon
  as the user changed the label or used an Arch derivative with a label that isn't
  compliant with FAT (e.g. Athena Linux), search, and therefore boot would fail.
* Also alter the code so that we modify for more than one token if needed.
* Closes #2086
