discoverable partitions support is broken

[kraxel]

Problem description

Commit 67bf130cd1da5372079810f87445dd70f26b3a24 has a bug, it sets the wrong uuid.

The gpt partition entries have /two/ guids. The partition uuid (which shows up in /dev/disk/by-partuuid), and the partition /type/ uuid. The discoverable partition uuids should go to the latter, the patch sets the former though.

Steps to reproduce the behaviour

fdisk -lx
[ ... ]
Device       Start      End Sectors Type-UUID                            UUID                                 Name     Attrs

The 4F68... discoverable partition uuid for the x86_64 root filesystem is in the UUID not the Type-UUID column

will fix it. I was not aware that the GUID setting is not enough
