pulse-server: use module-combine-stream for module-combine-sink
Implement the combine-sink module with the native module. Make sure we use the same logic to wait with emitting the module loaded signal until we have seen all the sink_inputs of our module. Make sure we also use the timeout to signal module failure when we don't see the nodes.
