part:efi: add GUID for linux file system data
Previously, Linux used the same GUID for the data partitions as Windows (Basic data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7). This created problems when dual-booting Linux and Windows in UEFI-GPT Setup, so a new GUID (Linux filesystem data: 0FC63DAF-8483-4772-8E79-3D69D8477DE4) was defined jointly by GPT fdisk and GNU Parted developers.

Historically there are 5 methods to generate this number. The oldest one is
combining machine's MAC address and timer (epoch) value.
