autotest: Perform cold reboot on test device to enable VM

There's an issue where some devices need to undergo a cold reboot in
order to reset the EC so a bit can get flipped to enable the VM. This
checks if the device supports VM functionality by testing the existence
of /usr/bin/vm_concierge and then if the cold reboot is needed by the
lack of /dev/kvm. If both those are true it uses ectool to do a cold
reboot.
