avformat/matroskadec: Add a workaround for missing WavPack extradata mkvmerge versions 6.2 to 40.0 had a bug that made it not propagate the WavPack extradata (containing the WavPack version) during remuxing from a Matroska file; currently our demuxer would treat every WavPack block encountered as invalid data (unless the WavPack stream is to be discarded (i.e. the streams discard is >= AVDISCARD_ALL)) and try to resync to the next level 1 element. Luckily, the WavPack version is currently not really important; so we fix this problem by assuming a version. David Bryant, the creator of WavPack, recommended using version 0x410 (the most recent version) for this. And this is what this commit does. A FATE-test for this has been added.
