pypy3 fails to build, can't find zlib

[mweinelt]

Broken after upgrading zlib from 1.2.11 to 1.2.12, because it can't find libz.

Currently on staging-next and release-21.11.

This is also most likely fixed by PR #167395. At any rate, I see it back up in (staging-next-)21.11: https://hydra.nixos.org/job/nixpkgs/staging-next-21.11/pypy3.x86_64-linux

[7c6f434c]

Overriding zlib fed to pypy37 with the patch from #167395 definitely lets the build succeed and the resulting executable runs

Resolved in all current channels.
