sepolicy: Relabel wifi. properties as wifi_prop

 * These properties are used by the wifi hal and it works as expected on
   devices with compatible property. However, on devices without
   compatible property, these prperties are labeled as "default_prop"
   because public/property_contexts is not used. Thus they can't be set
   by the hal.
 * To tackle the problem, label them as "wifi_prop" in
   private/property_contexts which also works on devices without compatible
   property. The label will be overridden later by
   public/property_contexts rules if exist.
