tdf#120341 OOXML export: fix export of Pie Chart Wall Borderline

Export LineStyle_NONE instead of default linestyle of PlotArea border,
because LibreOffice make invisible the Wall shape properties in case of
PIE/NET/FILLED_NET charts. Or other solution in the future is set the
default LineStyle of these charts to LineStyle_NONE.
