ob-core: Fix nil value of `org-babel-temporary-stable-directory'

Browse source 
* lisp/ob-core.el: Make sure that
`org-babel-temporary-stable-directory' is set to non-nil non-existent
directory.  Non-existent directory is required to avoid clashes when
multiple Emacs processes are running.

Fixes https://yhetil.org/emacs-devel/87sfnfhm6v.fsf@yandex.com
