Update track filter alg to handle standard tracks

This MR adds the InDetTrackTruthFilterTool to the TrackSystematicsAlg to enable the "track-killing" used by displaced vertex searches on standard tracks. The TrackSystematicsAlg is also then scheduled in the LLP1 derivation to write out a modified VSI container run on the systematically varied track container.

Note that this only modifies the LLP1 output for MC.
