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
