Add Gamecube to hash initialize iterator for iso format

[bozothegeek]

Just to add Gamecube now for 'iso' format in hash initialization for iterator. Thanks in advance for this merge. Tested in pixL (new retro OS ;-)

See for example of result when hash matched well now with any new retroarchivements for gamecube in this OS using pegasus-frontend and a modified GameOS theme including RA display...

Please also update the test_hash_gamecube function to initialize an iterator and validate the new code path.

@bozothegeek - have you had a chance to look at the unit test suggestion?
