    utils: Fix create_wrapper
    
    Wrappers generated by create_wrapper do not work properly:
    python, for example, looks at argv[0] to know if it is
    running from a virtualenv. Because the wrapper replaces
    argv[0] with python's canonical path, python cannot tell
    whether it has been invoked directly or from a virtualenv
    symlink.
    
    This change makes the wrapper pass the original argv[0] down
    to the real command.
