winmm waveOutGetPosition test

[Robert Reif]

Adds a test to check playback position after done playing.

This test is only executed in interactive mode.  It shows two
bugs in wine:  position in ms is not calculated accurately and
the wavemap device doesn't always calculate position in samples
properly.
