Remove obsolete configuration files

Running these with python produces errors indicating that they're not
used in any standard workflow and that probably they have been skipped
in some migration (maybe MeasurementTrackerEvent?).

The configurations
RecoPixelVertexing/PixelLowPtUtilities/python/MinBiasTracking_cff.py
RecoPixelVertexing/PixelLowPtUtilities/python/common_cff.py
RecoPixelVertexing/PixelLowPtUtilities/python/firstStep_cff.py
do not have problems as such, but are related to (and only to)
secondStep_cff.py and thirdStep_cff.py, which do have problems.
Remove MuonRoadTrajectoryBuilder

It is unused, extremely unlikely to be used in the future, and it is
currently the only TrajectoryBuilder-deriving class constructed by
ESProducer.
Remove TYPELOOKUP_DATA_REG(TrajectoryBuilder)

No more TrajectoryBuilder ESProducts
