While it shouldn't happen on regular guests, we sometimes hit it when fuzzing
within the guest, which would cause the lkvm process to exit - which is
undesired.
Our PIT tests were using the debug port to trigger a reboot. Instead of using
that port we now use the reboot line of our i8042 controller.

H. Peter Anvin suggested to use motherboard specific ports
for testing instead of ones well known. Thanks, Peter!

To make so we write any value to port 0 and
start kvm in --dbgtest mode so we are expecting
for this exit.
