Show biometric-specific dialog when appropriate

1) We need to pass a "restriction" string from settings to the dialog,
   otherwise the biometric dialog could be shown in non-biometric
   flows
2) Updates ActionDisabledByAdminDialogHelper to pass the restrition
   to be taken into consideration when creating the controller
3) Sets an optional onClickListener on the positive button.
