[PATCH weston] toytoolkit: Take into account transform when sending output allocation.

[Scott Moreau]

---

It seems only wscreensaver and tablet-shell use output_get_allocation(). This
fixes a problem when screensaver gets the wrong size for transformed outputs
where width and height are swapped.
