Since the webcam open function only returns the open fh on success, we need to close the FH ourselves in the event that the subsequent tests fail.
Testing:
iterate over all files in /dev/video* and attempt to open each one as a webcam
then log the details of said video device if successfully opened as a webcam.
This was used to find the initial leak of file handles, as a device which opend fine, but failed to be recognized as a valid webcam (supportsVideoCapture/ supportsVideoStreaming)the handle would be lost.
