[Halld-offline] problem with hdgeant4 over the weekend, farm and ifarm

[Mark Ito]

Folks,

Somehow, and I don't exactly what I did, I ended up corrupting our build 
of Geant4 (10.02.p02) for CentOS 7.7 (farm and ifarm) last Friday 
evening. This broke all publicly built hdgeant4 binaries due to 
inconsistencies with shared libraries from Geant4.

I restored Geant4 from a snapshot just now and the problem seems fixed.

Again, this started at around 9:30 pm, Friday, July 31 and was broken 
until just now, and was for farm and ifarm only. Sorry for any problems 
this may have caused.
