nixos/tailscale: warn if strict reverse path filtering is in use.

Tailscale uses policy routing to enable certain traffic to bypass
routes that lead into the Tailscale mesh. NixOS's reverse path
filtering setup doesn't understand the policy routing at play,
and so incorrectly interprets some of this traffic as spoofed.

Since this only breaks some features of Tailscale, merely warn
users about it, rather than make it a hard error.

Updates tailscale/tailscale#4432
