Explicitly specifies sin6_family & sin6_len of sockaddr_in6 for raw socket

Browse Source 
destination.
(Currently lack of their specification does not lead to any problem, because
 kernel does not check the consistency between actual address and its
 address family / length on raw socket.

 However kernel should always check their consistency and stop sending packets
 if there is a contradiction.  Considering backward compatibility of
 programs, I just fixed rtsol now;  I'd like to fix the kernel behavior later.)
