bug#57071: Xscreensaver not working since latest patch

[Tory S. Anderson]

I hit the same error. I began with the error and the fix from 
https://issues.guix.gnu.org/23286 and then put xscreensaver into my screenlock 
section of my config:

--8<---------------cut here---------------start------------->8---
(list (service gnome-desktop-service-type)
           ;(screen-locker-service xscreensaver) ;; this initializes, but 
shouts a "do not run as root" error instead of running my images, and doesn't 
accept my password
           ;;; other stuff
           )
--8<---------------cut here---------------end--------------->8---

Now I have 'xscreensaver: don't login as root' on my screensaver, and no 
images. As mentioned earlier, only the xscreensaver-auth program should be 
setuid, not the whole thing, apparently.
