image: always enable users module in anaconda

Unconditionally enable the users module in Anaconda.
The module serves two purposes:
- It will create a user that's defined in the blueprint by adding the
  user creation stage in the kickstart file.
- It allows users to create user accounts interactively during
  installation.
