system tests: friendier messages for 2-arg is()

The 'is' check was intended to be called with three arguments,
the last one being a nice helpful test name. There's a fallback
for two-argument calls, but it was a horrible FIXME.

New fallback: the most recently run podman command. We keep
track of it in each run_podman() invocation.

This is not ideal, because it's theoretically possible to
invoke 'is' on something other than the output of run_podman,
but this at least fixes the by-far-most-common case.
