matroskamux: fix matroskamux ! matroskademux

Browse source 
Don't carry over DISCONT flags from the input buffers to the
output buffer, or the demuxer might reset its state when it
receives the first data buffer just after parsing the simple
block header, and then expect sane data to follow.
Fixes matroskamux ! demux erroring out.
