73b3c8fc8c tstest/natlab/vnet: add IPv6 all-nodes support
This adds support for sending packets to 33:33:00:00:01 at IPv6
multicast address ff02::1 to send to all nodes.

Nothing in Tailscale depends on this (yet?), but it makes debugging in
VMs behind natlab easier (e.g. you can ping all nodes), and other
things might depend on this in the future.

Mostly I'm trying to flesh out the IPv6 support in natlab now that we
can write vnet tests.

ff1d0aa027 tstest/natlab/vnet: start adding tests
And refactor some of vnet.go for testability.

The only behavioral change (with a new test) is that ethernet
broadcasts no longer get sent back to the sender.
