ci: manifest: Define RPM artifacts for regular CentOS Stream 8 build

Commit 7360326 missed the fact that artifacts were only defined for the
libvirt Git type of libvirt-python build (git is cloned, libvirt is
built and then libvirt-python) based on the
'native_git_build_job_prebuilt_env' job template whereas libvirt CI
expects the RPM artifacts to come from a job based on the
'native_build_job' template instead.

Note that this patch is a hotfix to something which requires a proper
cleanup to stay consistent with the way we're handling the same thing
in libvirt-perl.
