Comment 14 for bug 308397

As the rationale for bug 430120 is to retrieve the same data as with update pings, we should feed the same locale info, i.e., the installed locale code, as it determines in http://mxr.mozilla.org/mozilla-central/source/toolkit/mozapps/update/src/nsUpdateService.js.in#519.

Not sure what info linux distro's have there, and what we do about that.
