Linux sandbox: Use /build instead of /tmp as $TMPDIR
There is a security issue when a build accidentally stores its $TMPDIR in some critical place, such as an RPATH. If TMPDIR=/tmp/nix-build-..., then any user on the system can recreate that directory and inject libraries into the RPATH of programs executed by other users. Since /build probably doesn't exist (or isn't world-writable), this mitigates the issue.
