combine-sink: Set origin_sink for each output stream

Browse source 
While the threading model for combine is different from other filters
(which expect to just piggy-back on the I/O thread of the most
downstream sink), it might still be valuable to set this field to
indicate that this sink input is intended to behave as a filter stream
rather than a conventional stream.

At the very least, routing behaviour and cycle detection should act on
these streams as with any other filter.
