[arale] embedded thumbnails not generated correctly

[Bill Filler]

This is arale only bug

Open camera-app and take picture
Go to photo roll
Notice the thumbnails are not at the correct aspect ration
use exiv2 to extract thumbnail out of jpeg and you can see the embedded thumbnail is not correct

This is from camera log

** The image and thumbnail aspect ratios are not equal. Thumbnails will display wrong!

I think this is basically the same issue we had with krillin, which I just pushed to arale. I already triggered a new build including this fix on the device side, so next image should have it.
