Subject: [PATCH] gen-manifest: include repo as pseudo package

This is one possible fix for the issue raised in
https://github.com/osbuild/otk/pull/209/files#r1771119550

I.e. how we can ensure that we have the same repo configuration
between images and otk.

It works by adding a pseudo package for each repo, the resulting
diff in otk looks like this:
```yaml
diff --git a/test/data/images-ref/centos/9/x86_64/qcow2/centos_9-x86_64-qcow2-empty.yaml b/test/data/images-ref/centos/9/x86_64/qcow2/centos_9-x86_64-qcow2-empty.yaml
