The replacement was automated with the following command:

   $ git grep -l ',gdk-pixbuf+svg)' \
     | xargs sed 's/(".*" ,gdk-pixbuf+svg)/("librsvg" ,librsvg)/' -i

* gnu/packages/gtk.scm (gdk-pixbuf+svg): Delete package.
(gtk+-2)[propagated-inputs]: Replace gdk-pixbuf+svg with librsvg.
(gtk+)[propagated-inputs]: Likewise.
* gnu/packages/gnome.scm (gdk-pixbuf+svg): Add deprecated package.
