chimera: Avoid integrity constraint violations on registering locations

When running 'pnfs register' on a pool to ensure that all files are registered,
PostgreSQL logs a warning about every file that was already registered. More
over, the transaction rollbacks appear to generate quite a lot of churn between
our master and slave instances.

This patch using a trick we already use when inserting new names in t_dirs:
Only insert when there is no existing record with the same key.
