This fixes a line in Z3950.pm, and adds a new test to 14-OpenILS-Utils.t

This also adds a new dependency, the perl module Test::Warn, which I've added to Makefile.install

Testing needed, particularly for Fedora. Thanks!

I'm not able to test Fedora.. but I have pushed sign-offs to working/user/berick/lp1190717-util-test-signoffs.

A made a small change to the Utils.t patch to avoid a new perl warning:

    --
    Bill moved the @comp_holdings variable declaration outside of the
    warning_like block to avoid a new warning:

    Name "main::comp_holdings" used only once: possible typo at
    t/14-OpenILS-Utils.t line 42.
    ---

Works fine. Sanity check appreciated.

Also added "libtest-warn-perl" to the squeeze/wheezy makefile mods for bug #1190279
