[BUGFIX] Set default units to mm in exportSld

The default units in QgsMapRenderer is Millimeters. The default units in SLD is Pixel but exportSld does not convert all millimeters in pixels. We notes this bug by comparing default QGS Server rendering and rendering with the SLD generated by QGIS. To resolve it, we just have to add units to the document element.
