Fix script generation macro

In the macro GENERATE_CBM_TEST_SCRIPT the Geant4 data variables were not
properly added to the generated shell script. This was not yet seen since all
tests were done with the Geant3 simulation engine. The problem was found after
the KF related tests were moved to  Geant4.
