Added new dual-use package PhysicsAnalysis/BPhys/BPhysTools to
the AthAnalysis and AnalysisBase packages' package_filter.txt files.
Also changed #ifndef pragma statement to #ifndef XAOD_ANALYSIS in
Event/xAOD/xAODBPhys/Root/BPhysHelper.cxx as had been done
in the corresponding header file in the previous commit.
