mpeg2dec: fix position query by trusting upstream

Browse source 
Position queries are badly handled for DVDs (probably due to the division in
chapters): the time returned was the time since the start of chapter.

Now ask upstream for position queries, fall back to the old code if upstream
cannot answer the query.
