gdk-pixbuf-query-modules segvs g_module_close()ing svg_loader.so on amd64.
This seems to be because of the call to rsvg_init() in svg_loader's
fill_vtable() method. The obvious fix is for svg_loader to call
g_module_make_resident() on itself, but this doesn't work here, because
gdk-pixbuf-query-modules doesn't fill in the "module" field in the
GdkPixbufModule.

Fix:
