tdf#150789 - FILEOPEN PPTX: fix text in SmartArt vertically off

Calculate correctly the textbox area of upArrowCallout and
downArrowCallout shapes in group shapes. In grouped list
text area does not cover the whole shape but just a part of it at the top.

In case of upArrowCallout and downArrowCallout the arrow size of the shape
is not included in the textbox area of the full shape.
