fftools/ffmpeg_mux: stop using filter_in_rescale_delta_last for streamcopy

That field was added to store timestamp conversion state for audio
decoding code. Later it started being used by streamcopy as well, but
that use is wrong because, for a given input stream, both decoding and
an arbitrary number of streamcopies may be performed simultaneously.
They would then all overwrite the same state variable.

Store this state in MuxStream instead.

This is the last use of InputStream in of_streamcopy(), so the ist
parameter can now be removed.
