buffers does not work with zink

Bug description:
[ Impact ]
An application is not draw if using GL and running in a wayland
compositor that doesn't support dmabuf (e.g. just shared memory).
This is happening with amd graphics, but I've read of reports with
intel.
See: https://gitlab.freedesktop.org/mesa/mesa/-/issues/11613
Fixed by: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30479
[ Test case ]
1. Install weston compositor
2. Install mesa-utils and gtk-4-examples
3. In a terminal run:
weston --renderer=pixman
4. In the weston terminal run:
gtk4-demo
4a. The application should start and show
5. In the weston terminal run:
eglgears_wayland
5a. The application should start and the gears spinning
[ Regression potential ]
swrast driver is used to render when proper hardware acceleration can
be used instead.
