fix: use instance property for CLLocationManager authorizationStatus

The class method +[CLLocationManager authorizationStatus] was
deprecated in macOS 11.0. Switch to the instance property instead.

Also fix the default case to return 'not determined' instead of
'denied' for kCLAuthorizationStatusNotDetermined.
