    pam_timestamp: fix typo in strncmp usage
    
    Before this fix, a typo in check_login_time resulted to ruser and
    struct utmp.ut_user being compared by the first character only,
    which in turn could lead to a too low timestamp value being assigned
    to oldest_login, effectively causing bypass of check_login_time.
    
    * modules/pam_timestamp/pam_timestamp.c (check_login_time): Fix typo
    in strncmp usage.
