Andrew Dunham 5708fc0639 wgengine/router: print Docker warning when stateful filtering is enabled
When Docker is detected on the host and stateful filtering is enabled,
Docker containers may be unable to reach Tailscale nodes (depending on
the network settings of a container). Detect Docker when stateful
filtering is enabled and print a health warning to aid users in noticing
this issue.

We avoid printing the warning if the current node isn't advertising any
subnet routes and isn't an exit node, since without one of those being
true, the node wouldn't have the correct AllowedIPs in WireGuard to
allow a Docker container to connect to another Tailscale node anyway.

Updates #12070
