Looks like UBSan still needs SdrObjGeoData's RTTI for some reason

After c02c4df9414ed2bef96565522238ca05013d3ac3 "make some classes
module-private", CppunitTest_services failed in my Linux ASan+UBSan build with

> .../postprocess/qa/services.cxx:318:(anonymous namespace)::Test::test
> forced failure
> - instantiating "com.sun.star.comp.oox.xls.ExcelFilter" via "com.sun.star.comp.oox.xls.ExcelFilter"  caused com.sun.star.loader.CannotActivateFactoryException "loading component library <file:///.../instdir/program/libscfiltlo.so> failed"

due to
