pull up fix to call kdb check-transited-path first

- pull up fix for not calling a kdb plugin's check-transited-path
  method before calling the library's default version, which only knows
  how to read what's in the configuration file (RT#7709, #1013664)

commit 0406cd81ef9d18cd505fffabba3ac78901dc797d
Author: Greg Hudson <ghudson@mit.edu>
Date: Wed Sep 25 10:40:23 2013 -0400
Support authoritative KDB check_transited methods
In kdc_check_transited_list, consult the KDB module first. If it
succeeds, treat this as authoritative and do not use the core
transited mechanisms. Modules can return KRB5_PLUGIN_NO_HANDLE to
fall back to core mechanisms.
