macos-builder02 in particular has been having problems for a while now
that no one could reproduce. We believe we have finally found the cause:
missing shebangs, not just in the tests themselves but *also* in the
inline scripts `nix-shell` itself writes.
Fixes#1042.
I believe this will also fix#1093.

As far as I can tell, there's no harm to let know a nix-shell invocation
about NIX_LOG_FD being stderr.
Fixes#336.

As far as I can tell, there's no harm to let stdenv know that they can
write to file descriptor 2 which is stderr inside of a nix3-develop
shell.
Contributes towards #336.

Alternative to cl/4661 discussed in #1044.
It can be assumed that `$tmpdir/build-top` can be created safely without
any risk, this way, we don't need to reuse the random directory creation
primitive.
Fixes#1044.

Instead of letting inner shell perform the cleanup, we will fork/execvp
and finish the work ourselves. Once an interruption arrives, we wait
again and return the exit status code of the inner shell.
This idea was suggested by eldritch horrors.
Fixes#1020.

This was always a terrible idea independently of whether it crashes.
Stop doing it!
This commit was verified by running nix-shell on a trivial derivation
with --debug --verbose to get the vomit-level output of the shell rc
file and then diffing it before/after this change. I have reasonable
confidence it did not regress anything, though this code is genuinely
really hard to follow (which is a second reason that I split it into two
fmt calls).

This change feels kind of gross and reveals a fair bit about the
disorganization of our tests, but I think it makes parts of it a bit
better.
