org-babel-load-file: Do not rely on `org-babel-tangle-file' making changes
* lisp/org.el (org-babel-load-file): Update modification time even
when `org-babel-tangle-file' does not actually modify the tangled
file. This makes sure that modify-time comparison logic does not make
Org re-tangle Org file that had been changed but the changes did not
affect the tangled code.
