gnu: emacs: Byte compile the site-lisp directory.

* gnu/packages/emacs.scm (emacs): Use the (gnu build emacs-utils) module.
Byte compile the site-lisp directory as part of the 'install-site-start'
phase.
(emacs-minimal, emacs-xwidgets, emacs-no-x, emacs-no-x-toolkit): Reset modules
to those of the gnu-build-system.
