-												tests/timeout: create output so tests don't trivially pass

Timeout tests rely on failed build to determine success,
so make sure these derivations (silent in particular)
don't fail regardless of timeout behavior.

-												Kill builds when we get EOF on the log FD

This closes a long-time bug that allowed builds to hang Nix
indefinitely (regardless of timeouts) simply by doing

  exec > /dev/null 2>&1; while true; do true; done

Now, on EOF, we just send SIGKILL to the child to make sure it's
really gone.
