OSX CALayer Stencil/.. Fix: In case of FBO CALayer usage, use default caps/pixelformat w/ chosen GLProfile only

Using a pixelformat w/ chosen stencil for CALayer does corrupt rendering for an unknown reason,
probably due to incompatible pixelformat w/ CALayer composition.

This patch simply discards any special chosen caps, while only recognizing the desired GLProfile
for the FBO CALayer pixelformat.
