SwFlyCntPortion::SetBase: adjust position of the textbox if necessary

In case of inline shapes, it's not possible to just copy the AnchorType
property of the shape to the textbox, as we want the textbox at the
expected position, not inline. OTOH, an inline shape has an implicit
position, so we can't position its textbox at import-time.

Solve the problem by setting the position of the textbox as we create
the layout of the inline shape.
