mtp: Allow to send SCCP/ISUP to a specific endpoint 

For a linkset define where SCCP/ISUP should be send. This config
should probably move up to the application part when real work on
the routing is done. Right now the sccp_opc/sccp_dpc need to stay
inside the mtp_layer3.c to be able to send a TFA for the reachable
OPC and it is easier to keep both (dpc/opc) in the same file.
