x11: Don't include X11/extensions/extutil.h We don't use it, it was a leftover from 1.2, I think, and it doesn't exist on Solaris, so this should hopefully fix the build there. This also means we don't need the configure/cmake checks for SDL_VIDEO_DRIVER_X11_CONST_PARAM_XEXTADDDISPLAY, so that was removed also. Fixes #1666.
