Gwich'in language typo

Derp. In file Open-ILS/src/sql/Pg/950.data.seed-values.sql, of course.

I know this is a simple change, but still removing milestone pending a branch and pullrequest.

Fixed in branch user/paxed/lp1158206

Tested by updating the item_lang coded value on our test server, using the syntax in the provided branch. Works as expected. Rebased to master, signed off. Thanks Pasi!

Works for me too, so I signed off in my working branch and added a new commit to handle the upgrade script to set the value properly in existing installations.

I pushed this, but the upgrade script it also missing the oils_i18n_gettext() call (similar to the other recently pushed branch). Will test and push a fix shortly.

As it turns out, the missing oils_i18n_gettext() shouldn't matter, since it is only used during the 'make' step of the build process, and that never happens for upgrade scripts (if I understand the basics of what Pasi told me).

In any case, a lot of upgrade scripts have oils_i18n_gettext() in them, and it never hurts to be consistent, so I went ahead and pushed my "fix" anyway.

As for the original bug, thanks to Pasi, Ben, and Remington for pitching in on it. Four sign-offs on the fix for what was likely a find-and-replace error; I love it :)
