Unit tests can't prove the rewritten binary actually works on each supported
distro and on both podman and docker; this exercises the real thing.
Move the tests in a set of simple scripts to run them.
Make a smaller e2e test for CLI and Images that runs on every PR
Keep the full compatibility suite in a separate job for main merge and
manual runs.
