This is very similar to tools/fetch-distro.py. The idea is that we extend the commit to update the mkosi hash with a git log --pretty=oneline output, so that the reader can know what changes were actually included. The motivation is that I'm always wondering what changed in mkosi when I see a commit updating the hash, and it's nicer to have this information shown directly in the commit. The script does _not_ pull changes from upstream, on the assumption that the person doing the commit always has a fresh checkout and that they tested with that checkout.
