Base backups reported checksum failures to pg_stat_database only for
files with more than one failing page. Commit 6b9e875f72 placed the
report inside the block emitting the per-file summary WARNING, which
was skipped for a single failure. As a result, a backup failing on
files with one corrupted page each left checksum_failures untouched.
To fix, emit the per-file summary and the pgstat report for any
non-zero failure count. The end-of-backup total WARNING had the same
off-by-one and is now also emitted for a single failure.
