gsdx-ogl: use only core debug extension 

There are 2 extensions GL_ARB_debug_output (promoted from amd extension)
and GL_KHR_debug (the core extension, promoted from GL_ARB_debug_output)

As we use the callback we could drop the manual query of errors.
And save us the load of the GL_ARB_debug_output extension function pointer.
