netlink: Use nl_pid 0 to play nice with others.
While the netlink field is named nl_pid, and typically contains a process id, setting it to a pid value directly prevents other modules from also using a netlink socket. On the other hand, setting it to 0 allows multiple modules to use a netlink socket by letting the kernel assign the nl_pid a value. This allows the verito tap code to interact nicely with the router plugin's librtnl after, say, tap-inject has been enabled.
