sw XHTML export: fix writing of section direction

The XHTML export behavior was the same as the HTML one for section text
direction, the <div dir="..."> markup was used.

This shares code with the HTML filter, but it's not valid in
reqif-xhtml, while the CSS markup would be fine: <div style="dir: ...">.

Fix the problem by keeping the behavior unchanged for HTML, but switch
to inline CSS for XHTML.

The other similar attribute was "id", but that's fine even in XHTML.
