Describe the bug

(Upstream issue: https://github.com/NixOS/nix/issues/7731)

The initialisation code in libstore (initLibStore()) unsets TMPDIR on Darwin, and resets it to /tmp. This code is invoked when running nix-shell interactively (among others), which means that applications which rely on TMPDIR for IPC (for example, emacsclient) break

Steps To Reproduce

Not yet reproduced with lix, however the original code from upstream is still present.
