veth: allow to setup multicast address for veth device
We can only setup multicast address for network device when net_device_ops->ndo_set_rx_mode is not null. Some configurations need to add multicast address for net device, such as netfilter cluster match module. Add a fake ndo_set_rx_mode function to allow this operation.
