libpayload/libcbfs: Add VBOOT_CBFS_INTEGRATION support
If LP_VBOOT_CBFS_INTEGRATION is enabled, then libcbfs will reboot with vboot failure in non-recovery mode on CBFS file hash mismatch. BUg=b:197114807 TEST=Build with VBOOT_CBFS_INTEGRATION enabled and boot on google/ovis4es device Change-Id: Ic0f62212b7217b384e8c4cbd9535fe4243301f8c Signed-off-by: Jakub Czapiga <jacz@semihalf.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/77726 Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com> Reviewed-by: Yu-Ping Wu <yupingso@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
