lisp/ob-julia.el: Use lexical-binding

* lisp/ob-julia.el: Use lexical-binding.
(ess-eval-visibly-p): Declare as dynamically scoped.
(org-babel-execute:julia, org-babel-julia-assign-elisp)
(org-babel-julia-evaluate, org-babel-julia-evaluate-session):
Remove unused references to `colnames-p' and `rownames-p'.

Thanks to Pedro Bruel for reviewing this patch.
