Goal: Re-enable logging and displaying failures on login when login is
      compiled with PAM and when FAILLOG_ENAB is set to yes. And create the
      faillog file if it does not exist on postinst (as on Woody).
Depends: 008_login_more_LOG_UNKFAIL_ENAB
Fixes: #192849

Note: It could be removed if pam_tally could report the number of failures
      preceding a successful login.
