Prepare for changes in Gaudi v40
- gaudi/Gaudi!993 (merged) replaced 2 "normal" warning messages with one info message in EventLoopMgr
- gaudi/Gaudi!1632 (merged) remove the support for legacy GaudiExamples test helpers (renamed as GaudiTestSuite)
This MR modifies a few references to take that into account.
I also added a missing link needed when building in a super-project context.
