tdf#163883 editeng RTF export: fix broken offsets into the para style table

Regression from commit 70d1bd6ee0eba9d6661cd6280566f77a87f2d068
(tdf#161652 editeng, RTF copy: only write used paragraph styles,
2024-06-20), type a few characters into the title placeholder shape in
Impress, switch to the Outline view, select all, copy, paste into
Writer: the resulting text nodes won't have paragraph styles, just
direct formatting.

Inspecting the produced RTF, the problem is that the styles table
started to omit unused styles, but the style -> offset mapping table
still included them, so the offset didn't match, which results in losing
the style on RTF import.

Fix the problem by building the mapping table later also also ignoring
unused paragraph styles there, to restore consistency between declaring
style entries and referring to them.
