Update ZFS scripts for archzfs compatibility

zfssnapshot:
- Change date format to YYYY-MM-DD_HH-MM-SS_description
  (matches pre-pacman snapshot format for consistent sorting)
- Convert spaces to underscores instead of hyphens
- Add GRUB menu regeneration after snapshot creation

zfsrollback:
- Add special warning for genesis rollback
- Add GRUB menu regeneration after successful rollback
  (removes destroyed snapshots from boot menu)
