fftools/ffmpeg: Take type limitations of AVFifo API into account

The types used by the AVFifo API are inconsistent:
av_fifo_(space|size)() returns an int; av_fifo_alloc() takes an
unsigned, other parts use size_t. This commit therefore ensures
that the size of the muxing_queue FIFO never exceeds INT_MAX.

While just at it, also make sure not to call av_fifo_size()
unnecessarily often.
