tdf121374 ooxmlexport: export H/F to default section

It wouldn't be terrible to duplicate headers/footers
unnecessarily, but it is terrible to have them disappear.
If the last SectPr has no idea about the section start,
it can't know whether it is continuous or started with
a page break. In that case, just ensure that the
header and footer are explicitly written out.

This seems to be a DOCX problem only. I think that
doc and rtf both write the section information at the
BEGINNING of the section, but DOCX writes it at the END.
So, sharing code between these two opposite approaches
is difficult.

A followup commit can try to make it smarter about
knowing the start of the section (because usually
pPDNd is zero).

Another followup commit can add the missing page breaks.
