Turn off fake DNS for request sent from Routing and Freedom outbound. Fake DNS now only apply to DNS outbound. This is important for Android, where VPN service take over all system DNS traffic and pass it to core. "UseIp" option can be used in Freedom outbound to avoid getting fake IP and fail connection.
