scripts: Split creating USB image to separate script

Browse source 
The USB image is not a required output, but becomes half of the total
size of the build artifacts as it creates copies of the firmware images.
Move the logic to a separate script so that CI will not contain it, but
users can create the image after building the firmware.

    ./scripts/build.sh <model>
    ./scripts/usb.sh <model>

Reduces the size of the ZIP archive created by Jenkins by ~50%.
