Fix podman network IDs handling

The libpod network logic knows about networks IDs but OCICNI
does not. We cannot pass the network ID to OCICNI. Instead we
need to make sure we only use network names internally. This
is also important for libpod since we also only store the
network names in the state. If we would add a ID there the
same networks could accidentally be added twice.

Fixes #9451
