avformat/filmstripenc: Use ff_raw_write_packet()

Browse Source 
The only difference of the currently used write_packet()-function to
ff_raw_write_packet() is that the former also counts the number of
frames. Yet doing so in the muxer itself is unnecessary as this is
already done generically in write_packet() in libavformat/mux.c.
