EcalBarrelScFiRecHits: Modify localDetFields and distance parameters (#2139)

### Briefly, what does this PR introduce?

Added "sector" to CalorimeterHitReco_factory::localDetectorFields for
EcalBarrelScFiRecHits so that EcalBarrelScFiRecHits will have local
coordinates in sector frame of reference.

With this, Island Clustering for EcalBarrelScFiProtoClusters works as
expected when it is based on the localDistXZ

### What kind of change does this PR introduce?
- [x ] Bug fix (issue #__)
- [ ] New feature (issue #__)
- [ ] Documentation update
- [ ] Other: __

### Please check if this PR fulfills the following:
- [ ] Tests for the changes have been added
- [ ] Documentation has been added / updated
- [ ] Changes have been communicated to collaborators

### Does this PR introduce breaking changes? What changes might users
need to make to their code?
No

### Does this PR change default behavior?
Local coordinate for ScFiRec hits will be in sector frame of reference
