pg_resetwal: Fix incorrect error message related to pg_wal/summaries/

A failure while closing pg_wal/summaries/ incorrectly generated a report
about pg_wal/archive_status/.

While at it, this commit adds #undefs for the macros used in
KillExistingWALSummaries() and KillExistingArchiveStatus() to prevent
those values from being misused in an incorrect function context.

Oversight in dc212340058b.
