nixos-help: bundle the desktop item with the script

Browse Source 
This is to ensure that whenever we install the desktop item we also have
the script installed. Prior to b02719a we always had the reference to
the script in the desktop item. Since desktop items are being copied to
home directories and thus "bit rod" over time that absolute path was
removed.
