ox-odt.el: Fix LaTeX formulae in opendocument exports

* lisp/ox-odt.el (org-odt--translate-latex-fragments): Apply signature
  change for `org-format-latex'.

Commit a24f339f58 changed the signature
for `org-format-latex' (lisp/org.el) to add `beg' and `end' optional
parameters.  This led to an error in ox-odt.el when exporting an
odt document containing LaTeX formulae.
