demux_mkv: fix relative seeks without index

Relative seeks didn't add the current position as they should. Fix.

Note that this had no effect in normal playback case even if the file
had no index, because the "accurate_seek" logic at higher level would
convert all commands to absolute seeks before calling demuxer level.
