demux_mkv: index all packets

Browse Source 
Instead of indexing only 1 packet per cluster (which is enough for
working seeking), add every packet to the index.

Since on seek, we go through every single index entry, this probably
makes seeking slower. On the other hand, this code is used for files
without index only (e.g. incomplete files), so it probably doesn't
matter much.
