sign_official_build: preserve /boot for legacy BIOS

Browse Source 
This patch checks for 'cros_legacy' in the kernel config, and skips
running strip_boot_from_image.sh if present.  This is because
'cros_installer postinst' on legacy BIOS relies on presence of /boot in
rootfs.

BRANCH=signer
BUG=b:20947354
TEST=Ran the script with devkeys, and checked presence of /boot in the
signed .bin file by mounting locally

$ ./sign_official_build.sh ssd chromiumos_image.bin ../../tests/devkeys \
    chromiumos_image_signed.bin ../../tests/devkeys/key.versions
