gettext tests: test message re-encoding under Shell

Our PO files are written in UTF-8, but We're not using
setlocale(LC_CTYPE, "") so it's not a given that someone with e.g. a
ISO-8859-1 locale will get messages in ISO-8859-1, and not UTF-8.

Introduce a new test to test for this, it uses the recently added
GETTEXT_ISO_LOCALE prerequisite.

This patch only tests the shellscript portion of our gettext
interface. I can't get any of these tests to fail on any of the
gettext implementations I have around, even without the previous patch
to gettext.c. But having exhaustive tests in this area is good
regardless.
