Zebediah Figura ddf3b93ac1 winegstreamer: Don't try to convert duration from byte length. 
This effectively reverts 613446d018.

Duration and convert queries, in general, appear to be handled by the first
upstream element that knows how. If two different elements respond to each
query, we may treat the byte duration of the whole file as if it were the
duration of a single stream, or treat an undecoded byte duration as if it were a
decoded byte duration.

The aforementioned commit was written in order to ensure that we receive a valid
duration for test.mp3 in quartz_test.exe, and is obviated by the previous
patches which retry duration queries until successful (or EOS).
