test(ilm): check the purge's history error end to end

The implementation review of the delete-all reporting found that no
committed test checked the error a purge returns on a drive whose
metadata does not decode: restoring the old read quorum error passed.
TestPurgeAllVersionsRefusesCorruptDrive now sends the purge through
DeleteObject and checks errDeleteAllHistoryUnavailable and its
SlowDownWrite mapping; with the old error it fails.

The HELP text of expiry_incomplete_total now says that the
tier_unsupported_skipped reason counts the scanner's per-drive
observations, not expiry attempts.
