[O] [bug, ox-latex] footnotes with math in narrowed buffer

Hi,

Consider the following example:

* h1
foo[fn:1]

* Footnotes
[fn:1] if \alpha $\beta$ \(\gamma\)

Narrow it to h1 and export the buffer.  Something like this is exported:

   foo\footnote{if \alpha \beta \gamma}

Somehow org-export-get-footnote-definition "knows about" math-blocks for
footnotes that are within the buffer view, but not outside.  The patch
fixes the above example, but I doubt it's the Right Wayᵀᴹ to fix this
(i.e. there could be a more fundamental bug).
