Restrict ArduinoISP name collision fix to ArduinoCore-API 1.0.1

ArduinoCore-API 1.0.1 declares a SPISettings class, but ArduinoCore-API 1.0.0 and 1.1.0 don't do this, so the previous preprocessor conditional that was added to fix the ArduinoCore-API sketch for platforms using ArduinoCore-API 1.0.1 actually breaks it for platforms using previous or later versions.
