  1. Filter namespace creation args to clone in default seccomp policy 

    Currently unshare is filtered by the seccomp policy mutator, but clone
isn't. This filters args to clone that can create a namespace, blocking
both ways of creating a namespace. This also unfortunately means clone3
has to be entirely disabled, because it's not possible to filter the
struct with cBPF.
