tdf#104035 RTF export: fix handling of absolute tab positions

RtfAttributeOutput::ParaTabStop() assumed that they are always absolute,
but WW8AttributeOutput::ParaTabStop() points out what compat setting
decides if they are absolute or relative.

(cherry picked from commit b5e871deb8ce390b9fa694e21b0272c7462da703)
