These changes look good to me. However, the fake_data_producer_test in daqsystemtest needed to be changed as a result. That change is in DUNE-DAQ/daqsystemtest#288.

Description
Resolves Issue #391 by having FakeDataProdModule use TimestampEstimatorSystem to produce timestamps using the DUNE-DAQ clock (getting the clock frequency from the Session's DetectorConfig object). These timestamps are used to create TimeSync messages only; the module uses trigger timestamps for any produced data Fragments.
