lockdown: Don't explicitly validate pairing unless we're dealing with an older device
On newer iOS version, ValidatePair is not mandatory to gain trusted host
status. Starting with iOS 11, the ValidatePair request has been removed from
lockdownd and will throw an error. This commit adds a version check so that
ValidatePair is only called on devices prior iOS 7.
