    Fallback to a rm -f action for podman

    There is a podman specific behavior that cannot be reproduced with
    docker:

    $ docker run -itd --privileged --name=foo busybox sleep 1000
    $ docker exec -it foo sh -c "sleep 180"
    $ kill -STOP <that process>
    $ docker stop foo
    $ docker rm foo

    works w/o errors, while podman fails the latter step:
    Error: cannot remove container <id> has active exec sessions: container
    state improper

    To make it consistent, add a fallback to re-try it with rm -f.
