MINOR: haterm: Don't init haterm master pipe if not used

There is no reason to initialize the haterm master pipe if haterm is not
used. So now, it is only performed if a non-disabled haterm frontend is
found. To do so, in addition to test the proxy's flags and capabilities, we
also check if "stream_new_from_sc" points on "hstream_new".
