key-init: If time resets, tell user to set it, but allow skipping

The 'warn' message was not very effective, because change-time.sh
clears the screen right after.  Prompt with whiptail instead, which
also lets the user know what's happening before we drop them into a
series of prompts.

Let the user skip changing time if they really want to.  While they
usually should set the time, it's rather frustrating if Heads forces
them to go through these prompts when they don't want to.
