We were previously only doing this for tailscaled-on-Darwin, but it also appears to help on iOS. Otherwise, when we rebind magicsock UDP connections after a cellular -> WiFi interface change they still keep using cellular one. To do this correctly when using exit nodes, we need to exclude the Tailscale interface when getting the default route, otherwise packets cannot leave the tunnel. There are native macOS/iOS APIs that we can use to do this, so we allow those clients to override the implementation of DefaultRouteInterfaceIndex. Updates #6565, may also help with #5156 Signed-off-by: Mihai Parparita <mihai@tailscale.com>
