update_kernel: Don't make fake bootloader stub in 'latest'
The build_image script isn't able to overcome the fact that
update_kernel.sh makes a non-symlink directory for 'latest' in the
images directory when it makes a fake bootloader stub. Usually this
isn't a problem because developers build an image first and then
update_kernel from it, but if you build an image after running
update_kernel you'll see that it fails to build the image when trying to
repoint the 'latest' symlink.
Make a bootloader stub in /tmp instead and remove it when we're done to
avoid this problem.
BUG=None
TEST=update_kernel to DUT without image, build_image after and see it
work
