    gnu: emacs-ert-runner: Fix lisp directory warning.
    
    This fixes the warning message such as: "Warning: Lisp directory
    '/tmp/guix-build-emacs-ert-runner-0.7.0-1.90b8fdd.drv-0/source': No such 
file
    or directory" that would be printed upon running ert-runner.
    
    * gnu/packages/emacs-xyz.scm (emacs-ert-runner)[phases]{install-executable}:
    Filter out the temporary source directory from the paths composing the
    EMACSLOADPATH variable used in the wrapper.
