[Matthias Clasen <matthiasc src gnome org>]

commit 54e7a94d7005ed8da0707154d3606dec96732ac9

    builder: Fix signedness issues in apis
    
    Whenever we take a length argument that can
    be -1 for 'nul-terminated', it should be
    gssize, not gsize.
    
    Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1555
