lockdown: Get DeviceClass to make sure OS version dependent code is executed correctly

The code in lockdownd_client_new_with_handshake would call the function
lockdownd_validate_pair based on the OS version being less than 7.0 without
taking into account that Watch OS has a different versioning scheme compared
to the other device classes. For this and any future version/device specific
checks, the code now queries the DeviceClass and stores it in the
idevice_private struct.
