    Fix double-close in ksu get_authorized_princ_names
    
    If list_union() fails due to an allocation failure, then close_time()
    will attempt to fclose users_fp and login_fp a second time.
    
    This bug was originally introduced in commit
    be95b52c2d0c21b1fe92f9f90166fc2fa8eecc95, and has been present in
    every krb5 release since 1.1.
    
    (cherry picked from commit 0b8c6f3e1e8e561aa56a7d4e2171320119991dae)
    
    ticket: 8768
