Disabled hardened build because it makes the linker fail with messages like
relocation R_X86_64_PC32 against undefined symbol `BZ2_bzWriteOpen' can not be used when making a shared object; recompile with -fPIC
See https://fedoraproject.org/wiki/Changes/Harden_All_Packages.
Right now it only tests whether seccomp correctly forges the return
value of chown, but the long-term goal is to test the full sandboxing
functionality at some point in the future.

We're going to use libseccomp instead of creating the raw BPF program,
because we have different syscall numbers on different architectures.
Although our initial seccomp rules will be quite small it really doesn't
make sense to generate the raw BPF program because we need to duplicate
it and/or make branches on every single architecture we want to suuport.

The SSHStore PR adds this functionality to the daemon, but we have to
handle the case where the Nix daemon is 1.11.
Also, don't require signatures for trusted users. This restores 1.11
behaviour.
Fixes https://github.com/NixOS/hydra/issues/398.
This was observed in the deb_debian7x86_64 build:

Calling c_str() on a temporary should be fine because the temporary
shouldn't be destroyed until after the execl() call, but who knows...
There is really no conceivable reason why building Nix would need
access to the host's nix.conf. If it does, it's a bug, and we should
fix that instead.
Thus, for example, to get /bin/sh in a chroot, you only need to
specify /bin/sh=${pkgs.bash}/bin/sh in build-chroot-dirs. The
dependencies of sh will be added automatically.
Sodium's Ed25519 signatures are much shorter than OpenSSL's RSA
signatures. Public keys are also much shorter, so they're now
specified directly in the nix.conf option ‘binary-cache-public-keys’.
The new command ‘nix-store --generate-binary-cache-key’ generates and
prints a public and secret key.
