Update ddeb-retriever to build an InRelease file

[Brian Murray]

Per Julian K:

Fixing ddeb-retriever to build an InRelease file solves that issue

Then one just needs by-hash for the index files and then you can just dump caching proxies in front of the backend and don't need to worry because stuff is accessed via unique paths so there's no caching issues

[Julian Andres Klode (juliank)]

It's just gpg --clearsign < Release > InRelease, isn't it?

The by-hash stuff is obviously more complicate, you need to retain old files and add new ones. I don't really know it all right now, needs research :)

Please move the main branch of that git repository into the ~ubuntu-archive group.

Here are the code changes to build InRelease files:

I have tested that locally to generate InRelease and that apt is happy about the generated archive.
