Include CNI networks in inspect output when not running

We were only including the CNI Network fields in the output of
`podman inspect` when the container was not running. It's simple
enough to fix (populate with empty structs, since we can't fill
anything without a CNI response to get IP address assigned, etc).

This is necessary for Docker compatibility.
