In generated fixed flash layout tarball, add manifest and signature
which can be used for code update by phosphor-software-manager.

        public key and their signatures.
        Verify that all.tar can be used to do code update by both
        legacy method (org.openbmc.control.BmcFlash.service) and
        phosphor-software-manager.
