Logs follow-until tests: loosen checks

...in hopes of fixing a flake with podman-remote. It's still
possible that there's a real problem with logs under remote,
and this will just sweep that under the rug.

Also, fix a nasty-red test warning (add cleanup), refactor
uses of $(pause_image), and improve a few test assertions.

Closes: #17286
