Use oox::drawingml::convertEmuToHmm()

And get rid of the writerfilter copy, that does no rounding.  Adjusted
testcases:

- testFdo80555: 245 -> 247 (should be 246.944444444, so a good change)
- testDMLGroupShapeChildPosition: roundtripped values are now closer to
the initial ones, so also a good change
