rust/client: Extend with more metadata for zincati

Add more metadata that zincati needs, like `base-commit-meta`
which includes the `fedora-coreos.stream` key and the cosa basearch,
etc.

Also `Derive(Debug)` since it's used in a cache struct that also
derives debug, and that's a friendly thing to do in general.
