xdg-desktop-entries: add module (#1450)

* xdg-desktop-entries: add module

rebase

* xdg-desktop-entries: adapt to changes in makeDesktopItem

This package depends on the makeDesktopItem function in nixpkgs, which recently changed its syntax:
https://github.com/NixOS/nixpkgs/pull/91790

This commit makes the module compatible with the new syntax.

It also exposes the fileValidation option in makeDesktopItem.
