Fix PackedCandidate::dz and PhotonIDValueMapProducer

[gpetruc]

• fix the dz(point) method of PackedCandidate to work correctly when point is not the associated PV, and the eta of the candidate is not the eta of the track. This ensures that cand.dz(point) is always the same as cand.track.dz(point) whenever the track is available (as it was already the case for dxy)
• fix the PhotonIDValueMapProducer on miniAOD to get the dxy and dz from the candidate instead of the track (dxy and dy are always available in the candidate, but they're not available in the track at low pT, and in 94X this causes an exception)

@gpetruc : should I expect any difference in the miniAOD output with this fix? I am not able to see any...

[gpetruc]

PhotonIDValueMapProducer should be transparent. dz should give tiny differences in rare cases but maybe the bugged version was not used anywhere in production.

• Fix for rare cases (no effect visible in jenkins or small size private tests)
• Code changes are in line with what in the description
