futility: rolled back vbutil_kernel change

When disabling verity with make_dev_ssh.sh, a bug in
vbutil_kernel caused the re-signed kernel size to be the entire
kernel partition instead of just the necessary bits. Until we can
improve the test coverage, I'm rolling back the changes that
introduced this bug.


Created a new test image with these changes. You can install it
and disable dm-verity and it works (although there seems to be an
unrelated browser startup issue on ToT).
