The simple solution here is to change the lines to 
confdir /home/USER/.guix-profile/etc/privoxy
logdir /home/USER/log/privoxy

If you want an untested user shepherd service, here's one I've come up
with on the spot:

(define privoxy
  (make <service>
  #:provides '(privoxy)
  #:docstring "Privoxy filters outgoing internet connections"
  #:start (make-forkexec-constructor
            '("/var/guix/profiles/per-user/USER/current-guix/bin/privoxy" "--no-daemon" "/home/USER/.config/privoxy/config")
            #:log-file "/home/USER/log/privoxy/privoxy.log")
  #:stop (make-kill-destructor)
  #:respawn? #t))
(register-services privoxy)

And then you'd add that to your ~/.config/shepherd/init.scm

I have at the bottom of mine:
;; Send shepherd into the background
(action 'shepherd 'daemonize)

(for-each start '(syncthing kdeconnect))

and at the top:
(use-modules (shepherd service))
