Add a seccomp filter to prevent creating setuid/setgid binaries
This prevents builders from setting the S_ISUID or S_ISGID bits, preventing users from using a nixbld* user to create a setuid/setgid binary to interfere with subsequent builds under the same nixbld* uid. This is based on aszlig's seccomp code (47f587700d646f5b03a42f2fa57c28875a31efbe). Reported by Linus Heckemann.
