Furquan Shaikh f274360326 fastboot: Add routine for verifying kernel image loaded in memory ...

This API allows fastboot boot from memory command to verify that the
image loaded in memory is signed properly using recovery keys. Thus,
only officially signed recovery images can be booted using fastboot
boot command in recovery mode.

However, if GBB_FLAG_FORCE_DEV_BOOT_FASTBOOT_FULL_CAP is set, then
this routine will not perform any check and return okay for any image
sent by fastboot boot.

BUG=chrome-os-partner:40196
BRANCH=None
TEST=Compiles successfully. With GBB override for FASTBOOT_FULL_CAP
set any signed image is allowed to boot. With FASTBOOT_FULL_CAP not
set, then only officially signed image is allowed to boot. (make -j
runtests successful)
