tdf#138302 partial revert tdf#108496: DOCX: redesign of override in lists

LO 6.4.5 commit	cf13fe3e6f6a40f6db064d65d4514d13a23a31f0
was only concerned about DOCX, but just elinated shared code.
So restore the shared code and just don't execute it for DOCX.

It doesn't look like RTF was working before this,
but this does fix DOC format.
I looked for existing unit tests in rtf and doc,
but none were found that hit this code.
