migration from EDFilter to stream::EDFilter (JetVertexChecker)

there are modules used @HLT which still need to be migrated and be multithread safe

this is the migration of the module JetVertexChecker

I agree with Chris.

It's also not quite expected to have this level of changes in a PR called "migration from EDFilter to stream::EDFilter"

(maybe in the end it wasn't such a bad idea to have separate PRs, since not all changes turn out to be trivial)
