pkgs/build-unity: Create desktop entry

This automatically creates a desktop entry based on the given fullName
and the standard path for the icon (Resources/UnityPlayer.png).

Well, at least I hope that the icon path is standard, but we'll see once
we use buildUnity for more games.

Tested using Plasma 5 for Invisigun Heroes.
