Mesa annotates the GL version string with "(Core Profile)" when using the OpenGL 3 core profile and so our heuristics that try and determine what vendor and GPU is being used where being confused. This updates the check_mesa_driver_package() function to consider this optional annotation. This adds a small unit test to verify the parsing of some example version strings. We can update this with more real world version strings if the format changes again in the future.
