net/captivedetection: exclude ipsec interfaces from captive portal detection (#13598)
Updates tailscale/tailscale#1634

Logs from some iOS users indicate that we're pointlessly performing captive portal detection on certain interfaces named ipsec*. These are tunnels with the cellular carrier that do not offer Internet access, and are only used to provide internet calling functionality (VoLTE / VoWiFi).

attempting to do captive portal detection on interface ipsec6
```

This PR excludes interfaces with the `ipsec` prefix from captive portal detection.
