[PATCH net-next 3/4] wireguard: selftests: load nf_conntrack if not present

["Jason A. Donenfeld" <Jason@zx2c4.com>]

From: Hangbin Liu <liuhangbin@gmail.com>

Some distros may not load nf_conntrack by default, which will cause
subsequent nf_conntrack sets to fail. Load this module if it is not
already loaded.

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

[ Jason: add [[ -e ... ]] check so this works in the qemu harness. ]
