Che-Liang Chiou 75ac2beb67 Add transitional flag for enabling arm kernel signing
For now arm kernel partitions are not signed. This CL is a transitionsl.
That is, the added flag should be removed after arm verified boot is stable.

To properly create an arm kernel partition, we also need another CL for
vbutil_kernel utility that turns off x86-only modifications on kernel
image. See CL:6538015.

BUG=chromium-os:3790,chromium-os:12352
TEST=see below

Build images for x86 and arm successfully, and notice that load_kernel_test
passes for x86 and signed arm image.
