[tor-commits] [arm/release] Wizard components for a startup option

    Wizard components for a startup option
    
    This adds platform detection and a check for the system torrc option for the
    wizard startup option. However, this still isn't enabled nor is the option
    implemented (so this has no impact on users). I'm suspecting that system
    startup is a bigger can of worms than I'd like to open right now, even if
    restricted to Debian and Ubuntu platforms so gonna leave the rest unimplemented
    for now...
