demux: disable stream cache if no tracks are selected
Slightly helps with timeline stuff, like EDL. There is no need to keep network (or even just disk I/O) busy for all segments at the same time, because 1. the data won't be needed any time soon, and 2. will probably be discarded anyway if the stream is seeked when segment is resumed. Partially fixes #2692.
