Module gaol::platform::linux::seccomp

seccomp-bpf support on recent Linux kernels.

This works in tandem with namespace in order to implement sandbox profiles. It is generally the weaker of the two approaches, because BPF is limited, but it’s useful for reducing kernel attack surface area and implementing coarse-grained policies.
