Michael Brown c6b299df20 [efi] Hold off watchdog timer while running
UEFI platforms may provide a watchdog timer, which will reboot the
machine if an operating system takes more than five minutes to load.
This can cause long-lived iPXE downloads (or interactive shell
sessions) to unexpectedly reboot.

Fix by resetting the watchdog timer every ten seconds while the iPXE
main processing loop continues to run.
