[librsvg: 3/5] Reduce include search paths to the "include" directory

[Federico Mena Quintero <federico src gnome org>]

    Reduce include search paths to the "include" directory
    
    Making it impossible for rsvg-convert, gdk-pixbuf-loader and
    gtk-doc to include any non-public headers by not having them
    in the search path seems like a good idea.
