jpeg-utils: Shift/fake also Exif.Image.DateTime
Turned out the Exif.Image.DateTime key may contain original timestamp
in some cases, e.g. when using extracted EXIF data from original image.
Since we can't trust this key has ever been modified by a photo software,
let's modify it together with other keys. It comes with a cost of changing
correct timestamp but we can't really distinguish that.
