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
