gnu: emacs: Byte compile the site-lisp directory, without coupling.

Browse Source 
This re-instates what the previously reverted commit did, but without adding
a dependency on the (guix build emacs-utils) module.

* gnu/packages/emacs.scm (emacs)[phases]{install-site-start}: Define a
EMACS-BYTE-COMPILE-DIRECTORY procedure, and use it.
