    build: add an option in the Windows installer to disable update check.
    
    This will allow to use the official Windows installer directly in the
    Windows Store, as per the new proposed workflow by Microsoft.
    
    Nevertheless our GIMP for Windows has a built-in update check which
    would check if a new version exist and warn people (advising them to go
    on the website and download the new installer to update). We obviously
    don't want this on the Windows Store which has its own update channel.
    It would be confusing.
    
    Therefore I added a feature to disable the built-in update check (not
    even showing in Preferences) by tweaking a single package variable. The
    installer now comes with new option /DISABLECHECKUPDATE=true which will
    add said variable.
