ui/gtk: Only try to initialize EGL/X11 if GtkGlArea failed

The commit referenced below changed the logic by causing the gtk-egl
backend to be initialized regardless of whether GtkGlArea initialization
succeeded. This causes eglInitialize to crash in Wayland systems without
XWayland.

This patch restores the previous logic.
