demux_lavf: always set packet duration
Makes WebVTT actually work. Also simplify the logic for setting duration. Only the subtitle path uses the packet duration, so the checks for STREAM_SUB as well as the keyframe flag are redundant. Apparently duration and convergence_duration are the same thing, but convergence_duration was added as Matroska-specific hack to get a higher value range (int vs. int64_t) with high resolution Matroska timebases. For us it doesn't matter, because double floats are used for timestamps and durations.
