jack: improve jack-sink and jack-source

Browse source 
Add more properties to sink/source to make them always process and
have the right priorities. Make sure the sink has higher priority than
the source so that we can pull in samples through the graph.

Only trigger the graph cycle when driving the graph.

Make sure to return something from process to signal that the graph can
continue processing.
