Theora signals "Output last frame again" with an empty packet.
To keep the behaviour of 18f24527eb of ignoring side data only packets, as
generated by the FLAC encoder to propagate updated extradata, also check for
pkt->side_data_size to choose wheter to mux the paket or not.
Fixes part of ticket #11451.
