Denton Gentry bcea88da46 wgengine: support FreeBSD with IPv6.
Fixes https://github.com/tailscale/tailscale/issues/1307 for keepsies.

We cannot set the tun interface address as a /128 on FreeBSD,
due to https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=218508
Instead we set the interface address as a /48, which is enabled
by commit 82edf94df72a52bcdc95fe37b20217e6003d92c0.
