Michael Brown 81e3351b9b [efi] Disable EFI watchdog timer when shutting down to boot an OS
The UEFI specification mandates that the EFI watchdog timer should be
disabled by the platform firmware as part of the ExitBootServices()
call, but some platforms (e.g. Hyper-V) are observed to occasionally
forget to do so, resulting in a reboot approximately five minutes
after starting the operating system.

Work around these firmware bugs by disabling the watchdog timer
ourselves.
