The Port.Pid was always more of an implementation detail on some
platforms and isn't necessary on Linux so it was never populated.
(Nothing outside the portlist package ever used it)
But might as well populate it for consistency since we have it in
memory and its absence confused people.

Partially reverts 1bd3edbb46 (but keeps part of it)
iptables is almost always required but not strictly needed. Even if
you can technically run Tailscale without it (by manually configuring
nftables or userspace mode), we still now mark this as "Depends"
because our previous experiment in
https://github.com/tailscale/tailscale/issues/9236 of making it only
Recommends caused too many problems. Until our nftables table is more
mature, we'd rather err on the side of wasting a little disk by
including iptables for people who might not need it rather than
handle reports of it being missing.

Instead of just falling back to making a TCP query to an upstream DNS
server when the UDP query returns a truncated query, also start a TCP
query in parallel with the UDP query after a given race timeout. This
ensures that if the upstream DNS server does not reply over UDP (or if
the response packet is blocked, or there's an error), we can still make
queries if the server replies to TCP queries.
This also adds a new package, util/race, to contain the logic required for
racing two different functions and returning the first non-error answer.

And use slices.Equal in wgengine/router too. (found while looking for callers)

(e.g. removing our certstore replace in 6d6cf88d82 or wireguard-go

go.mod replace in non-root modules, often because people are using tsnet

1.50.0 switched containerboot from using `tailscale up`
to `tailscale login`. A side-effect is that a re-usable
authkey is now re-applied on every boot by `tailscale login`,
where `tailscale up` would ignore an authkey if already
authenticated.
Though this looks like it is changing the default, in reality
it is setting the default to match what 1.48 and all
prior releases actually implemented.
