They were scattered/duplicated in misc places before.
It can't be in the client package itself for circular dep reasons.

Instead of having the CLI check whether IP forwarding is enabled, ask
tailscaled. It has a better idea. If it's netstack, for instance, the
sysctl values don't matter. And it's possible that only the daemon has
permission to know.

Without this, `tailscale status` ignores the --socket flag on macOS and
always talks to the IPNExtension, even if you wanted it to inspect a
userspace tailscaled.
