generators: rework mount generators
- Add support for finding and mounting /srv based on GPT data, similar to how we already handly /home. - Share the fsck logic between GPT, EFI and fstab generators - Make sure we never run the EFI generator inside containers - Drop DefaultDependencies=no from EFI mount units - Other fixes
