avformat/matroskadec: avcodec/tta: Set extradata_size to 22 

Up until c4e0e314, the seek table has been included in the tta
extradata, so that the size of said extradata was 22 (the size of a TTA1
header) + 4 * number of frames. The decoder rejected anything below a
size of 30 and so the Matroska demuxer exported 30 byte long extradata,
of which only 18 were set (it ignores a CRC-32 and simply leaves it at
0). But this is unnecessary since said commit, so reduce the size to 22.

Furthermore, replace 30 by 22 in a comment about the extradata size in
libavcodec/tta.c.
