[perl-Gnome2-Rsvg] Adjust the Cairo rendering methods

[Torsten Schönfeld <tsch src gnome org>]

commit 69cb45e4bcf1071205c09f18f3a7c6406bbc4b54
Author: Torsten Schönfeld <kaffeetisch gmx de>

    Adjust the Cairo rendering methods
    
    As of librsvg-2.0 >= 2.22, rsvg_handle_render_cairo and
    rsvg_handle_render_cairo_sub return booleans.  Adapt the wrappers.  Also, allow
    undef for the id argument of render_cairo_sub.
