Update Player instantiator API

Now servo/media player requires a new parameter for its creator, which
is a trait object that provides the GL parameters needed for setup the
generation of frames as GL textures.

This patch provides a dummy GL context trait object where the code
path will go to the default of raw frames.

Webaudio test expectation also were changed, adding two new failing
tests.
