h264_mp4toannexb: fix pps offfset fault when there are more than one sps in avcc
the pps offset is used to locate pps in the spspps_buf; however, the
current calc method is wrong because it is the offset of the original
avctx->extradata;
when there is only one sps in the avcc; the value is correct by
coincidence, however, it will
fail in avcc with multi sps
