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.
