OpenBSD doesn't support `lutimes`, but does support `utimensat` which
subsumes it. In fact, all the BSDs, Linux, and newer macOS all support
it. So lets make this our first choice for the implementation.
In addition, let's get rid of the `lutimes` `ENOSYS` special case. The
Linux manpage says

> The kernel does not support this call; Linux 2.6.22 or later is

which I think is the origin of this check, but that's a very old version
of Linux at this point. The code can be simplified a lot of we drop
support for it here (as we've done elsewhere, anyways).

Nix fails to build on OpenBSD with a linking error due to a non-found
symbol in boehm-gc. Just disable the GC until we can find a proper
workaround.

OpenBSD dynamic libraries never link to libc directly.
Instead, they have undefined symbols for all libc functions they use
that ld.so resolves to the libc referred to in the main executable.
Thus, disallowing undefined symbols will always fail

This overall seems like insecure tmp file handling to me. Because other
users could replace files in /tmp with a symlink and make the nix-shell
override other files.

I.e. when not all entries underneath a directory X follow eachother,
but there is some entry Y that isn't a child of X in between.
Fixes#11656.

This method is marked as `noexcept`, but `enqueueFileTransfer()` can
throw `Interrupted` if the user has hit Ctrl-C or if the `ThreadPool`
that the thread is a part of is shutting down.

When working on speeding up the CI,
I triggered a race condition in the creation of the tarball cache.
This code now instead will ensure that half-initialized repositories
are no longer visible to any other nix process.
This is the error message that I got before:
error: opening Git repository '"/Users/runner/.cache/nix/tarball-cache"': could not find repository at '/Users/runner/.cache/nix/tarball-cache'

This is better for privacy and to avoid leaking netrc credentials in a
MITM attack, but also the assumption that we check the hash no longer
holds in some cases (in particular for impure derivations).
Partially reverts 5db358d4d7.

Since #8766, invalid base64 is rendered in errors, but we don't actually
want to show this in the case of an invalid private keys.
