Non-managed profiles autoapply USER_SETUP_COMPLETE

Profiles, other than managed profiles, typically do not go through
SetupWizard or have a DPC-guided setup flow. Consequently, there is no
app that sets the USER_SETUP_COMPLETE secure setting for them, which
leads to oddities.

For such profiles, we should automatically consider them as being "setup
complete", so we set the USER_SETUP_COMPLETE setting as creation time.
