test: make hub container self contained

Instead of building on the existing quay.io/osbuild/koji:v1, and
then replacing a lot of it (entry point), move the packages and
the dnf.conf change over from the former base and then directly
depend on Fedora. This gives us more control, especially over
what Fedora version is being used.
