Correct the geometry for HGCal v4 in runTheMatrix (148xx workflows)

@bsunanda, @vandreev11

Note that as well as changing the reco geometry to V4, the sim geometry also has "Muon" appended to match the command given in @vandreev's email on the 08/Jul/2014.  If this is not what you want let me know.

Workflow 14800 (4 muons) runs through to the end, I'll do more tests once the pull request is in the queue.
