This patch makes gdk-pixbuf look for additional modules in a list of files
specified by the environment variable "GUIX_GDK_PIXBUF_MODULE_FILES".
A similiar patch for "GDK_PIXBUF_MODULE_FILES" had been sent to upstream:
https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/merge_requests/180
We use a "GUIX_" prefixed one to avoid breaking foreign programs:
https://issues.guix.gnu.org/63853
https://issues.guix.gnu.org/75523
Upstream-status: N/A
