With newer version of macosx and/or XCode the Geant3 code compiles without
problems but when it comes to memory allocation during runtime the execution
crashes. Up to now the underlying problem couldn't be identified.
Change CI tests such that on macosx only Geant4 is used. On Linux still Geant3
is used as simulation engine.

Bugfix for 2-station CFV MVD which corrects number of sensors in 2nd station.

Hits across sensors for 2 station MVD.

Rational:
- was introduced because bare-metal OS on virgo and virgo2 is centOS + debian containers were not immediately available stable
- now both vae23 (debian10) and vae24 (debian11) are available and well established/used by CBM virgo users
- these two jobs were responsible for ~50% of all pipeline failures due to something hanging up in the load_libraries test at a cost of 2 x 900 s

kfp-online: linking ROOT::Hist and ROOT::MathCore, changed the dependency on CbmKFParticle<Online/Offline>Interface to PUBLIC

- using a KFParticle version with no ROOT dependencies

- V0Finder:
  - YAML config
  - cuts on velocity of pion and proton candidates
  - enhanced cut for decay length (0.1 -> 5 cm)
