Changes are:
- Properly detect GPT disklabels and create proper BIOS boot partitions
if necessary.
- Return exit code 100 if reboot is required due to the kernel not
picking up the new partition table.
- Don't include BIOS boot partition in GRUB devices.

This fixes two issues:
- Don't _always_ print out NixOS configuration, only when explicitly
requested with -p.
- Add GRUB boot devices to NixOS configuration output.
