Subject: [PATCH] Add pg_verifybackup test for tar-format WAL verification

The new tar-format WAL verification in pg_verifybackup had no test
coverage for the case where pg_basebackup produces a separate
pg_wal.tar (--format=tar --wal-method=stream).  Add a test that takes
a tar-format backup and verifies it.
