Skip copying existing vendor images 

add_img_to_target_files.py has an option of "-a" to add missing
images only. Under this option, the script should skip copying
the radio images for A/B devices when given image exists already
under "IMAGES/".

Test: Run the command on an A/B device, the existing radio images under "IMAGES/" don't get overwritten; and missing images are added correctly.
