wireguard: add WireGuard kernel module and tools

WireGuard is an extremely simple yet fast and modern VPN that utilizes
state-of-the-art cryptography. It aims to be faster, simpler, leaner,
and more useful than IPSec, while avoiding the massive headache.

The recipes add the current experimental snapshot v0.0.20170421
out-of-tree kernel module and tools. The kernel module has some kernel
configuration dependencies such as some configuration part of
features/netfilter/netfilter.scc, hence netfilter.scc should be part
of KERNEL_EXTRA_FEATURES (which is the case by default).

Since wireguard-tools is TUNE_PKGARCH and depends on wireguard-module
which is MACHINE_ARCH (like all kernel modules) we need to add this
dependency to SIGGEN_EXCLUDE_SAFE_RECIPE_DEPS.
