[DD4hep] Disable DT Geometry Builder unit test that can't work with new DD4hep

[cvuosalo]

The new version of DD4hep uses the Geant4 units convention. The validateDTGeometry_cfg.py unit test in the Geometry/DTGeometryBuilder package compares a reference geometry that may have the ROOT units convention with the current geometry that has the Geant4 units convention. This comparison somehow triggers a ROOT exception complaining about changing the units convention. Discussion with the DD4hep developers indicates there is no easy fix. Rather than block the new version of DD4hep, it was decided to disable this unit test. In the future, we may figure out a way to fix it, but it doesn't seem to be essential.

PR validation:

With the changes in this PR, the Geometry/DTGeometryBuilder unit tests were run successfully in a special build with the new version of DD4hep.

No backport is needed.
