CUDA EL8 repo is misisng some modularity metadata

hi all,

we are trying to mirror/sync the nvidia cuda el8 repos into (redhat)
however, the synchronisation fails and after raising the issue with
redhat they pointed us to an existing bugzilla

it looks like the modularity spec was wrong/incomplete, and that correct
modularity metadata requires some more metadata that what the nvidia
repository currently provides.

it would be nice if someone from nvidia could have a look at it ;)
