ip/tunnel: Unify setup and accept zero address for local/remote endpoints

It is fully legal to submit zero (INADDR_ANY/IN6ADDR_ANY_INIT)
value for local and/or remote endpoints for all tunnel drivers:
no need additionally check this in userspace.

Note that all tunnel specific code already can pass zero address
to the kernel.
