fftools/ffmpeg_demux: skip finished/unstarted streams in readrate_sleep()

Browse Source 
This shouldn't affect the actual behavior, as the initialization of ds->dts
(implicitly zero'd) and the previous calculation of stream_ts_offset
guarantees that the `if (pts <= stream_ts_offset) continue;` branch fires.

Mainly a minor clarification of the code for the upcoming refactor.
