QNX: Evaluate mm-renderer buffer status

In the playing (or paused) state the media status should reflect the
buffer state, it should not stay in the loaded media state.

Mm-renderer differentiates between buffer "status" and "level".
Unfortunately, QMediaPlayer's buffer status maps to mm-renderer's
buffer level.
