img_from_target_files.py used to handle the case that a given TF.zip not
containing the image entries under IMAGES/. That is only the case for
pre-Lollipop releases.
Also unzip the needed files only since we know that for sure now.
Test: img_from_target_files.py with an existing bullhead-TF.zip gives
the same bullhead-img.zip.
