Let's make A/D CTF hard to host <3 #55

Easy to add seccomp rules and deploy, hard to prevent players from using it.

If combined with return-address-specific filter to functions like open, system. Oops.

Slick! It'd be cool to see this generalized to let rules be specified via environment variables in the future.

Could you rename the leftover "desock" functions to "deexec"?
