firstboot: Prompt for secret during firstboot welcome
- A freshly installed FreedomBox can be hijacked by a third party and an admin
  account can be created which can be used to inject malware or simply take over
  the instance. Password protecting the firstboot step is a good way to avoid
  this. A secret will be displayed to the user as soon as the Plinth package
  is installed, which they have to enter during firstboot welcome step. Also,
  writing this to a file in plinth's home in case the user loses it.
- This protection is not applicable for images built by freedom-maker and for
  Amazon Machine Images.
