run --rmi test: make it work

The recently-added 'run --rmi' test was not actually doing
what it thinks it was doing: for one, 'run_podman | grep'
is never going to work; also, the test was leaving behind
stray images.

Rework to do what I believe the intention was; and, combine
into one test (down from two) for readability.
