output/cursor: fix buffer size when nested and scaled 

The Wayland, X11 and headless backends don't really care about the
cursor size. We were picking a size identical to the texture size
in that case. This is incorrect for LoDPI cursor textures on HiDPI
outputs: in that case, we need to scale up the cursor texture.

Fixes the cursor being chopped off under the Wayland backend with
scale > 1.
