Backport of 8191acda7 as requested in ALIROOT-6439

Move call of AliEMCALEMCGeometry::DefineSamplingFraction from
AliEMCALEMCGeometry::Init() to AliEMCALv0::CreateGeometry(); change AliDebug to
AliInfo to check the sampling factor set in DefineSamplingFraction;
Modifications needed for Geant4.

Compared to 8191acda7 files were in a different location.
