    healthchecks: check if fact is defined before checking its value

    When checking if keystone/nova healthchecks are healthy, make sure the
    registered fact is set (which can slip to a further retry if podman
    inspect took too much time to execute).

    That way, we process the retries without an error like found in the bug
    report.
