contrib/lisp/org-export: Add footnote number to footnotes definitions collection 

* contrib/lisp/org-export.el
  (org-export-collect-footnote-definitions): Change key to footnote
  number, retrieved with `org-export-get-footnote-number'.  Also, do
  not use beginning position as label for inline footnotes, as those
  are weak identifiers.
