[Gptfdisk-general] add GPT partition types for Haiku

[Alexander v. G. IV <kal...@un...>]

While the topic of UUID additions is open, I threw a request out a while ago
on adding the Haiku GPT UUID's but never heard back on it.

42465331-3BA3-10F1-802A-4861696B7521  "Haiku BFS"

Can be confirmed in the Haiku source code, and on wikipedia...

Thanks!
