Unity 2017.2 uses UnityEngine.XR namespace, fix in InputTrackingPositionProvider

[Christian Oeing]

The namespace of InputTracking changed, adjust the script so no auto update is required:

#if UNITY_2017_2_OR_NEWER
    using InputTracking = UnityEngine.XR.InputTracking;
    using XRNode = UnityEngine.XR.XRNode;
#endif

Fixed by #if for UNITY_2017_2_OR_NEWER and changing the #if UNITY_EDITOR into a normal if switch that Unity can convert.
