Cherry-pick: ARM: enable kernel signing by default

This commit is a part of transition to enable ARM kernel signing. It is
at first an option that is enabled manually, and then (in this commit)
enabled by default. After more tests, the scripts that generate unsigned
ARM kernel partition will probably be removed.

BUG=chromium-os:12352
TEST=./build_image && load_kernel_test -b 2 /path/to/chromiumos_image.bin /usr/share/vboot/devkeys/recovery_key.vbpubk
