Subject: [PATCH 2/3] pseudo_util: modify interface to pseudo_etc_file

* Make the search directory pointers const: there is no reason why this
  function should be allowed to mutate the directories.

* Change the search directory argument from an array of pointers to a
  pointer-to-pointers to prepare for an upcoming enhancement.

Upstream-Status: Pending
