At the time of this writing (see future patches for this bug) the only
things we're using from sandbox/linux/seccomp-bpf/ are codegen.cc and
basicblock.cc, and the header files they require. However, we may use
more of this code in the future, and it seems cleaner in general to
import the entire subtree.
