[gtk-doc/ignore-gobject-deprecations] Ignore deprecation warnings when scanning types

[Emmanuele Bassi <ebassi src gnome org>]

commit b679cb0641bda58860fb783465f1600dbf576172

    Ignore deprecation warnings when scanning types
    
    We annotate deprecated types, which means we get compiler warnings when
    scanning them. This, coupled to -Werror or similar mechanisms, breaks
    the build when generating the documentation.
