podman system prune support prune unused networks

This is an enhancement for the podman system prune feature.

In this issue, it is mentioned that 'network prune' should be
wired into 'podman system prune'
https://github.com/containers/podman/issues/8673

Therefore, I add the function to remove unused networks.
