Make RunTier0Tests.py project agnostic
As @jchapman discovered, RunTier0Tests.py in non CI mode only works in Athena, but not in AthSimulation. I made the release detection project agnostic by:
- Using
AtlasVersioninstead ofAthena_VERSION - Using
LCG_PLATFORMinstead ofAthena_PLATFORM
I suppose our platform naming is always compatible with the LCG one.
@amete, this will need your approval.
