    rust: fake a git executable for test
    
    As git now has rust recommended, it's just troubling to have a circular
    dependency with the "requirement" of git for testing rustc as we are not
    building from a git repo and git won't be really useful anyway.
    
    Maybe this should be raised upstream.
    
    BTW update the reason of the short-ice failure as the upstream has
    figured out why it fails.
