Re: bin/58016: wg-userspace(8) requires explicit route setup

If I just create an unopened tun(4) instance, the same thing happens,
so it's probably a tun(4) issue rather than a wg(4) or wg-userspace(8)
issue:

# ifconfig tun1 create
# ifconfig tun1 inet 10.2.0.2/24
# ifconfig tun1 inet6 fd02::2/64
# ifconfig tun1 up
# ifconfig tun1

        status: down
        inet6 fd02::2/64 ->  flags 0x8<DETACHED>
        inet 10.2.0.2/24 ->  flags 0x4<DETACHED>
