Recent updates to the generic builder have caused haskellPackages.lmdb-simple to
fail to build on Darwin, since it cannot see the lmdb C dynamic library included
by its dependent haskellPackages.lmdb.

The C dynamic library has suffix `.so` not `.dylib`, so this fix allows for
that.

Closes #80190, but that issue may identify a preferable solution.

haskell generic-builder: fix Darwin regression for lmdb

postgresql: 9.5.20 -> 9.5.21, 9.6.16 -> 9.6.17, 10.11 -> 10.12, 11.6 -> 11.7, 12.1 -> 12.2

The current version seems to accelerate AES and SHA families.

Size increase on x86_64 is <10k in our case.

It can make quite some performance difference; I tried
$ time ./result-dev/bin/nettle-hash -a sha256 /some/file/around/2G
And the total CPU time went down from 8.5s to 2s (single thread).
Now it matches the time of openssl
$ time openssl sha256 /some/file/around/2G
Of course, in real life it will be much harder to notice a difference...

Platforms without support for this (e.g. i686) seem to still build fine,
and ARMv7 cross-build also succeeds for me, so hopefully all is OK.

This reverts commit 2d6f0cb.

postgresql versions < 9.5 have been removed from nixpkgs.

Execute in subshell so that the cwd returns back
to the original directory. This is important as
it enables pythonImportsCheck to work with checkPhase
