Relax GTP header validity check by allowing 1 sector size usable
LBA area (gh_lba_start == gh_lba_end) and allowing either or both
of gh_lba_start and gh_lba_end to exceed the size of the disk the
GPT currently inhabits.

Reduces false negatives and inappropriate fall through to MBR
spoofing and allows repair of otherwise valid GPT.
