This reverts commit 9e10898, after finding out that buildfarm members
running SLES 15 on z390 complain on the compression and decompression
logic of the new test: pipistrelles, barbthroat and steamerduck.
Those hosts are visibly using hardware-specific changes to improve zlib
performance, requiring more investigation.
Thanks to Tom Lane for the discussion.
