CHERRY-PICK: Fix squeezing of ndarray of corners when there is only one corner
OpenCV returns corners in ndarray with dimension as [num_corners, 1, 2].
We want to squeeze it to smaller dimension as [num_corners, 2].
The original method is np.squeeze(), which yields wrong results when
num_corners = 1.
BUG=chrome-os-partner:19584
TEST=Manually; use a white paper to cover camera and try to show only one corner
