* lisp/autorevert.el: Use lexical-binding. Fix hook usage.

(global-auto-revert-ignore-buffer, auto-revert-notify-modified-p)
(auto-revert-notify-watch-descriptor): Use defvar-local.
(find-file-hook, auto-revert-tail-mode, )
(auto-revert-notify-add-watch): Use setq-local.
(auto-revert-notify-add-watch): Don't call make-local-variable on
kill-buffer-hook (bug#20601).
