gnome3.gnome_control_center: fix thumbnailers path

Just like Nautilus (see #29970), GNOME Control Center also uses gnome-desktop for generating thumbnails. In particular, it tries to make a thumbnail from a file choosen as a profile picture, and when it does not succeed, it will not allow that file to be chosen. Of course, whithout a thumbnailer, it will always fail. https://github.com/GNOME/gnome-control-center/blob/43129a1cfd30374c3ff45c54eae9ee5cd68ae1b6/panels/user-accounts/um-photo-dialog.c#L190-L192 Since gnome-desktop scans `thumbnailers` directories under the paths in `XDG_DATA_DIRS`, gdk-pixbuf had to be added to the path to provide access to image thumbnailer. (cherry picked from commit a093bf8)
