[MSE][GStreamer] Set a minimum sample duration

[Alicia Boya García]

The last sample of the audio track in the asset used in this test player has a tiny duration (100 ns):

So small, we are truncating it to zero. We're not supposed to have frames with zero duration an. Instead, lets set a minimum frame duration for those fringe cases.

I'd recommend moving this above to a more prominent position than inside this method.
