demo: podman: New port forwarding behaviour for pasta, minor fixes

Reflect the recent changes in the Podman adaptation (no port
forwarding by default).

It turns out that by running two iperf3 processes, sometimes
slirp4netns blocks the second connection until the first test is
done, thus doubling the throughput. Use a single process for
slirp4netns with slirp4netns port handling.
