    giscanner: fix alias resolution
    
    Atk has a "typedef GSList AtkAttributeSet", which causes
    an ast.Alias() targeting a ast.List(). The latter has a
    target_fundamental of '<list>', which cannot be looked
    up in ast.type_names (because it's not a real fundamental
    type), and that breaks the build.
    
    It turns out that we don't need to find the fundamental
    type and then the fundamental type node - the target
    field of the ast.Alias already points to the desired
    type node.
