    Use new meta_key_binding_is_reversed() method
    
    Now that mutter gives a way to check if a MetaKeyBinding was marked as
    'reversed' or not, gnome-shell does not have to hardcode that a
    MetaKeyBinding using a shift modifier is reversed, it can directly check
    if the appropriate flag is set.
