patch 9.2.0052: Wayland: hiding lower half of command line in tiny vim

Problem:  Running gvim with a tiny build under a Wayland compositor
          hides the bottom half of the command line
          (dezza, after v9.1.1585).
Solution: When Wayland display protocol support is not compiled in
          (HAVE_WAYLAND not defined), force the X11 GDK backend to avoid
          display issues. This restores the gdk_set_allowed_backends("x11")
          call that was removed by patch 9.1.1585, but only for builds
          without Wayland support (e.g. tiny builds, see patch 9.1.1565)
          (Hirohito Higashi)
