Tracker broken in release 4.0.8

[nitsch]

The switch to OpenCV 3 broke the tracker. This is what running test_tracker.exe, MSVC 2017 x64, release 4.0.8 on Windows 10 spits out before dying:

Opening controller 0
[PSMOVE WARNING] Magnetometer in xx:xx:xx:xx:xx:xx not yet calibrated.
Calibrating controller 0...OpenCV: terminate handler is called! The last OpenCV error is:
OpenCV(3.4.8-pre) Error: Bad argument (Array should be CvMat or IplImage) in cvGetSize, file C:\projects\psmoveapi\external\opencv\modules\core\src\array.cpp, line 1246

This is likely due to the known issues occurring when trying to build/use these newer branches of OpenCV as C library (see opencv/opencv#6221 for example).

Similarly, on Linux:

Trying to init PSMoveTracker...OpenCV Error: Bad argument (Bad image header) in cvCloneImage, file /build/opencv-ytxPbe/opencv-3.2.0+dfsg/modules/core/src/array.cpp, line 3129
terminate called after throwing an instance of 'cv::Exception'
what(): /build/opencv-ytxPbe/opencv-3.2.0+dfsg/modules/core/src/array.cpp:3129: error: (-5) Bad image header in function cvCloneImage

Aborted

The issue on Linux was something different, fixed in 39eb996.
