podman inspect show exposed ports

Podman inspect has to show exposed ports to match docker. This requires
storing the exposed ports in the container config.
A exposed port is shown as `"80/tcp": null` while a forwarded port is
shown as `"80/tcp": [{"HostIp": "", "HostPort": "8080" }]`.

Also make sure to add the exposed ports to the new image when the
container is commited.

Fixes #10777
