cmd/runqemubuildlet: restart unresponsive qemu processes

Expose the healthz port from the buildlet running under QEMU, and
periodically check it for a successful response. If it has been failing
for longer than ten minutes, try to restart the VM. This should
successfully restart VMs that failed to boot, failed to shut down, or
are otherwise unresponsive.

For golang/go#47018
