fix sd_export_ooxml2 fail on Linux-rpm_deb-x86@71-TDF, MASTER

due to rounding differences, it was failing on 32bit linux only.

Test name: SdOOXMLExportTest2::testTdf919993_rotateShape
equality assertion failed
- Expected: 1449000
- Actual  : 1448640

Test name: SdOOXMLExportTest2::testTdf114845_rotateShape
equality assertion failed
- Expected: 3287520
- Actual  : 3287160

I also re-added the extra test that had previously
failed for a similar reason under Linux64 even.
