emacs: Factorize searching for Emacs packages.
* emacs/guix-emacs.el: (guix-emacs-directories): New procedure. (guix-emacs-find-autoloads-in-directory): Rename to... (guix-emacs-find-autoloads): ... this. (guix-emacs-load-autoloads): Remove. Replace with... (guix-emacs-autoload-packages): ... this. New procedure. At first, find a list of directories with Emacs packages, then add them to 'load-path' and finally, load autoloads. * doc/emacs.texi (Emacs Initial Setup): Adjust accordingly.
