emacs: Find autoloads in "guix.d" subdirectories.

Co-authored-by: Federico Beffa <beffa@fbengineering.ch>.

* emacs/guix-emacs.el (guix-emacs-find-autoloads-in-directory,
  guix-emacs-subdirs): New functions.
  (guix-emacs-find-autoloads): Search for autoloads in "guix.d"
  subdirectories.
  (guix-emacs-load-autoloads): Add subdirectories to 'load-path'.
* emacs/guix-init.el.in: Do not add guix emacs directory to 'load-path'
  because it will be done by 'guix-emacs-load-autoloads'.  Move
  requiring 'guix-emacs' from the top-level to a clause for checking for
  'guix-package-enable-at-startup'.
