xAODDataSource Unittest Fixes, master branch (2020.05.29.)
This is meant to fix the unit test errors coming from xAODDataSource in the x86_64-centos7-gcc8-opt and x86_64-centos7-gcc8-dbg nightlies.

The issue in the debug nightly is strictly speaking because of: https://sft.its.cern.ch/jira/browse/ROOT-10777 But following the work done in !33004 (merged), !33096 (merged) and !33176 (merged), one can work around that issue by generating some additional dictionaries. In this case the unit tests were failing with:

(gdb)So the solution was to generate a dictionary for SG::AuxTypeVectorFactory<ElementLink<Trk::SegmentCollection> > as well. And while at it, I also cleaned up the CMake configuration of the TrkSegment package.
The final issue (showing up in the optimised build) is because of some other ROOT issue that we didn't even open a bug report about. But that can also be worked around, with the included "hack". (Will follow up with the ROOT developers later on about that issue.)
