[PATCH weston] xwayland: Stack windows on top when activating them

[Jasper St. Pierre]

Now that we've removed the XYToWindow handler in Xwayland, we actually
have to stack windows properly. This stacks windows on top when
activating them.

Note that for a fully robust Xwayland implementation, we'll need a
complete stack tracker implementation, unfortunately.
