[PATCH] emacs: Fix reference to directory variable

Hello,

I noticed that guix's emacs mode contained a bug which prevented my full
emacs config from loading... turns out it was due to a variable
reference to a variable which had recently been renamed, thus turning a
small warning message into an unintentional error! :)

A small fix is below.

Subject: [PATCH] emacs: Fix reference to directory variable

* emacs/guix-emacs.el (guix-emacs-find-autoloads): Fix variable
  reference to 'elisp-root-dir', which kept the old name of 'dir'
  despite having been renamed above.  This had introduced a bug
  where a mundane warning would instead cause a variable reference
  error.
