runtime-rs: reduce generate_netdev_fds() dependencies

Browse Source 
generate_netdev_fds() takes NetworkConfig from which it however only needs
a host-side network device name.  This commit makes it take the device name
directly, making the function useful to callers who don't have the whole
NetworkConfig but do have the requisite device name.
