Update OSX and iOS bundle info plist.

Set the iOS initial device orientation and status bar flag to match with what will be set programatically later to avoid unwanted artifacts during app launches. Also set the new iOS key "UIRequiresFullScreen" to opt out from iOS 9 Slide-Over and Split-View. User making non-gaming apps using Urho3D may want to remove this iOS key though.
