tdf#118528 sw layout: only direct formatting for EmulateTableKeep

Emulating MSWord's way of keeping a table with the next paragraph
has caused a few complaints, but never anything that seemed
to clearly indicate a real problem - usually just badly designed
documents. But a common theme has been the keep attribute coming
through styles. Since our export-emulation writes directly
to the paragraph properties, lets make the emulation dependent
on direct formatting to avoid some of these complaints.
