wayland/buffer: Fall back to CoglTexture2DSliced

Browse Source 
XWayland creates buffers of the combined size of all connected displays.
This can, especially on older but still in use hardware, exceed the limits
of the GPU.

If that is the case, use `CoglTexture2DSliced` instead of `CoglTexture2D`
