[PATCH net-next v5 2/2] samples/bpf: Add test/example of using bpf_probe_write_user bpf helper

This example shows using a kprobe to act as a dnat mechanism to divert traffic for arbitrary endpoints. It rewrite the arguments to a syscall while they're still in userspace, and before the syscall has a chance to copy the argument into kernel space. Although this is an example, it also acts as
