On sparc64+ext4, suppress test failures from known WAL read failure.
Buildfarm members kittiwake, tadarida and snapper began to failfrequently when commits3cd9c3b andf47ed79 added tests of concurrency, butthe problem was reachable before those commits. Back-patch to v10 (allsupported versions).Discussion:https://postgr.es/m/20220116210241.GC756210@rfd.leadboat.com

Returns true if $tmp_check is subject to a sparc64+ext4 bug that causes WAL
321+
readers to see zeros if another process simultaneously wrote the same offsets.
322+
Consult this in tests that fail frequently on affected configurations. The
323+
bug has made streaming standbys fail to advance, reporting corrupt WAL. It
324+
has made COMMIT PREPARED fail with "could not read two-phase state from WAL".
325+
Non-WAL PostgreSQL reads haven't been affected, likely because those readers
326+
and writers have buffering systems in common. See
