FullSimLight to support different Geant4 versions - starting from Geant4.10.1
With this MR FullSimLight package can be compiled against earlier versions of Geant4 (i.e. Geant4.10.1). This is needed for benchmarking purposes, as Geant4.10.1 was the default version used in Atlas during the MC16 MonteCarlo simulation campaign.
