TS-2168: keep records.config in sync with RecordsConfig.cc at all time

According a long discussion on TS-2168 ticket:

"Since we can't make it conditional on records.config, doing it only in
RecordsConfig.cc makes it impossible to properly implement the verification
features that was requested in a different ticket" -- Leif

Let's remove #if TS_USE_RECLAIMABLE_FREELIST to keep records.config in
sync with RecordsConfig.cc at all time.
