This change fixes an issue where the re-bootstrapping process would overwrite a newer bootstrap manifest with one that it generates using its older minibp. It fixes the issue by only generating a new bootstrap manifest right after rebuilding minibp (as part of the bootstrap process). It then uses an additional rebootstrap iteration to replace the old bootstrap manifest with the new one. Change-Id: I16bad2f30f6ad7f10da07d77105e8745adec3650
