avcodec/pthread_frame.c: keep the last_pkt_props from worker threads in sync with the user context

Making it point to the input packet results in different behavior during flush,
where its contents will be that of an empty packet instead of containing the
props from the last input packet fed to the decoder.
After this change, decoding with more than one thread will shield the same
results as using a single thread.
