matroskademux: fix AV1 caps when there's no codec_data

Browse source 
There is no "byte-stream" format for AV1 in Matroska, this
was probably cargo-culted from H.264. codec_data / CodecPrivate
is now mandatory for AV1 in Matroska[*], but there are sample
files out there which don't have it (e.g. some Elecard ones).
