clutter: fix compilation when building without X11 backend

If Clutter is building the Wayland backend but not the X11 backend, the Cogl
support doesn't get enabled so the Wayland backend (which uses it) fails to
compile.

Backport a fix from upstream to fix this situation.

+Subject: [PATCH] build: Enable Cogl support with Wayland
+
+The Wayland backend is based on Cogl, so we need to turn on the
+SUPPORT_COGL flag to avoid breaking the build; this always went
+unnoticed because we usually build the Wayland client backend
+with the X11 backend.
