ox-odt: Stop adding leading space after line break

* lisp/ox-odt.el (org-odt-line-break, org-odt-plain-text): Remove
newline after line-break tag.

The exporter was pretty-printing the ODT XML with newlines after
forced line breaks, but LibreOffice would interpret those as
spaces.  This led to a leading space after every manual line break.

org-element: Use `org-latex-regexps', not `org-format-latex-options'

* lisp/org-element.el (org-element-latex-or-entity-successor,
  org-element-latex-fragment-parser): Use `org-latex-regexps' instead
  of `org-format-latex-options'.
* testing/lisp/test-org-element.el: Fix tests.

`org-latex-regexps' defines the correct syntax for LaTeX code within
an Org buffer.  On the other hand, `org-format-latex-options'
determines which syntax can be previewed within the buffer.
