Subject: [PATCH net] selftests: wireguard: load nf_conntrack if it's not present

Some distros may not load nf_conntrack by default, which will cause
subsequent nf_conntrack settings to fail. Let's load this module if it's
not loaded by default.

Fixes: e7096c131e51 ("net: WireGuard secure network tunnel")
