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 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.
