[Gptfdisk-general] Haiku GUID patch

[kallisti5 <kal...@un...>]

The Haiku project has defined a new GUID to identify it's GPT partition 
table entries.

Attached is a patch to the latest gptfdisk code to utilize this new 
GUID.

You can verify the same GUID in our code:
http://cgit.haiku-os.org/haiku/tree/src/add-ons/kernel/partitioning_systems/efi/efi_gpt.cpp#n48

And on Wikipedia (not really hard proof :) )
https://en.wikipedia.org/wiki/GUID_Partition_Table

The 0xeb00 is the old BeOS partition type we generally use on MBR 
systems.

Thanks!
