*_Emulation.ttcn: Specify destination when replying on procedure ports

procedure ports (like message ports) require us to specify the
destination of a message ("reply") in case it is connected 1:N and not
just 1:1.  This didn't show up as a problem so far, as we typically only
had one component talking to those procedure ports at any given point
in time.
