This adds support for:
"Linux filesystem data" 	0FC63DAF-8483-4772-8E79-3D69D8477DE4

Previously, Linux used the same GUID for the data partitions as Windows
(Basic data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7).
The new GUID (Linux filesystem data: 0FC63DAF-8483-4772-8E79-3D69D8477DE4)
was defined jointly by GPT fdisk and GNU.
