[OE-core] [PATCH] clutter: fix compilation when building without X11 backend

[Ross Burton]

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.
