Can now run multiple OscarMTProducers in the same job

[Dr15Jones]

PR description:

This was needed to test generating GEN+SIM in mixing module to generate pileup on the fly. The problem is Geant4 requires that it be initialized on one and only one thread which means all instances of OscarMTProducer must share that thread.

PR validation:

Code compiles. Test of on-the-fly pileup succeeded.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @perrotta, @dpiparo, @rappoccio (and backports should be raised in the release meeting by the corresponding L2)
