Add the possibility to specify plugin set to be used as overridable `thunar` derivation argument. New nixos config attribute: `services.xserver.desktopManager.xfce.thunarPlugins` that allows user to specify plugins in the context of nixos. Tests: - With and without plugins. - Using the nixos attributes.
