security/vboot: Add a dedicated flag for building of vboot library
As discussed in CB:35077, since both measured boot and verified boot depends on vboot library, it had better to introduce a dedicated flag CONFIG_VBOOT_LIB to control the building and linking of the vboot library, and make other flags needing vboot library select it. Only the actual verification stuff should be conditional on CONFIG_VBOOT.
