libpayload: Add vboot and reboot utility functions
Patch adds:
- vboot_fail_and_reboot() for vboot failures handling.
- reboot() weak implementation for payloads to implement, used
by vboot_fail_and_reboot().
- vboot_recovery_mode_enabled() to check if recovery mode flag is set in
vboot context. Implemented for future libcbfs implementation
of VBOOT_CBFS_INTEGRATION in libpayload.
