Workaround GLEW error code when calling glewInit() on Wayland

Browse source 
* Fixes OpenGL on Wayland when the GLX flavor of GLEW is linked
* Only if SDL2's video driver is "wayland" we also allow the
  GLEW_ERROR_NO_GLX_DISPLAY error code to be accepted as if glewInit()
  actually succeeded
* Hopefully this won't be needed anymore on future versions of GLEW when
  glewContextInit() is made part of the public API
