In this particular case, we can actually fix Emacs. When Emacs 
spawns a child process it passes the environment as specified in 
the process-environment variable, so you can clear out the 
unwanted environment variables by running something like this 
during startup:

(setq process-environment
     (seq-remove (lambda (s)
                   (or (string-prefix-p "GTK_PATH=" s)
                       (string-prefix-p "XDG_DATA_DIRS=" s)))
                 process-environment))

That doesn't solve the broader problem in Guix, but it should make 
Emacs in particular work properly.
