It's not a problem: we just need to install *.el files in
".../share/emacs/site-lisp/guix.d/ess" instead of
".../share/emacs/site-lisp/ess" as it is done by default.  The attached
patch should fix it.

A side note: this is one of the reasons why I don't like "guix.d"
sub-directory.  I think it is a useless extra level in the file
hierarchy.  If we used:

  .../share/emacs/site-lisp/<package>

instead of the current choice:

  .../share/emacs/site-lisp/guix.d/<package>

there would be no need to adjust 'emacs-ess', 'magit' and probably some
other packages to install *.el in "guix.d".  But this is for another
discussion :-), sorry:
