avformat/av1dec: Flush BSF upon seeking

The av1_merge_frame BSF outputs its cached data when it sees the
beginning of a new frame, i.e. when it sees a temporal delimiter OBU.
Therefore it typically has a temporal delimiter OBU cached after
outputting a packet.

This implies that the OBU demuxer must flush its BSF upon seeking
because otherwise the first frame returned after a seek consists
of an old temporal delimiter OBU only.
