This is no longer necessary since we have resolved most conflicts with
SDL2's version of the GL constants.

-Subject: [PATCH] Build: Disable nebu using SDL's glext.h constants
-
-SerenityOS provides glext.h definitions inside GL/gl.h, but the
-build process thinks that glext.h doesn't exist, therefore it attempts
-to use SDL's definitions, which leads to a conflict. Therefore, disable
-use of said definitions.
