You're better off setting your device to lock when the power button is pressed, or when the screen times out. Why would you want to authenticate the user when attempting to lock the device?

I guess to answer your question, an app could be made which would (when open) request a fingerprint, then lock the device. I expect no such app exists. You might be able to set something up with Tasker.
