Fix exiting Emacs after saving a tutorial

Browse source 
* lisp/tutorial.el (tutorial--starting-point): Make it
permanent-local, so that saving the tutorial to some file doesn't
kill this buffer-local variable.  Otherwise, trying to exit Emacs
after saving the tutorial will signal an error, because
'tutorial--starting-point' is void.  (Bug#37326)
