Gating tests: many fixes

1) Ugh. Update the podman test scaffolding so it invokes
    the magic 'loginctl enable-linger' command necessary
    for rootless podman to work.

    1a) [minor] update the rpm-versions and environment dump

 2) Bring gating.yaml up-to-date, including (ugh) duplication
    that will help us avoid maintenance burden when we fork f33
