    configure.ac: remove the check for a "too new" gdk-pixbuf version
    
    We are way past the 2.31 that was in the check, and unfortunately we
    can't get rid of the deprecated inline pixbufs until GIMP 3.0, so just
    kill the useless check for good and never define
    -DGDK_PIXBUF_DISABLE_DEPRECATED.
