tdf#142881 XLSX import: fix shapes rotated exactly 45°,

135°, 225° and 315° by correcting their cell anchor points,
like MSO does. Previously the XLSX export with the bad
anchor points messed up the rotation of the shapes, resulting
also broken text content in LO and MSO.

Thanks to Regina Henschel for analyzing the problem.
