system tests: the catch-up game

- run test: minor cleanup to .containerenv test. Basically,
  make it do only two podman-runs (they're expensive) and
  tighten up the results checks

- ps test: add ps -a --storage. Requires small tweak to
  run_podman helper, so we can have "timeout" be an expected
  result

- sdnotify test: workaround for #8718 (seeing MAINPID=xxx as
  last output line instead of READY=1). As found by the
  newly-added debugging echos, what we are seeing is:

      MAINPID=103530
      READY=1
      MAINPID=103530

  It's not supposed to be that way; it's supposed to be just
  the first two. But when faced with reality, we must bend
  to accommodate it, so let's accept READY=1 anywhere in
  the output stream, not just as the last line.
