Duncan Laurie eab2668a1a futility: Verify linux kernel signature ...

Verify the linux kernel signature on images before assuming
they contain a linux kernel.  This allows non-linux images
on x86 to be left unmodified when signed.

BUG=b:38040849
BRANCH=none
TEST=sign a multiboot kernel image that remains unmodified, and
ensure that x86 linux kernels are still updated properly and
can still be booted.
