[gobject-introspection] Enumerations can be negative

[Colin Walters <walters src gnome org>]

commit 6f6b2beb6918a83336dfdf94adde1d251dff84f3
Author: Colin Walters <walters verbum org>

    Enumerations can be negative
    
    Change the internal type for ValueBlob to gint32, since it's perfectly
    valid for enumerations to have negative values.
