[gobject-introspection] giscanner: prefer "except X as e" over "except X, e"

[Dieter Verfaillie <dieterv src gnome org>]

commit 2806ee7c7db81be0ad164caf68b70163df24386d
Author: Dieter Verfaillie <dieterv optionexplicit be>
Date:   Wed Oct 31 17:37:47 2012 +0100

    giscanner: prefer "except X as e" over "except X, e"
    
    It's more readable and as an added bonus Python 3 compatible.
