tegra: include tegra flasher utils into release image

Since the sd card image won't bootup on a device which has been flashed
with different version of L4T, include flasher utils that can be used to
flash the image into the device as well.

The new prepare-image.sh script will use the SD card image to create
an image that can be flashed into the device. This saves user from
downloading matching image from NVIDIA or bitbaking a flashable image.
