[gobject-introspection] scanner: Properly parse recursive list type nodes

[Colin Walters <walters src gnome org>]

commit f99dee8efd9fd3125273b644b7ebea98626eb664

    scanner: Properly parse recursive list type nodes
    
    Previously we were just looking for <type> inside a GLib.List,
    but it may be <array>.
    
    See bug 637262 for code that triggered this.
