Add test coverage for the bug reported in QTBUG-124898 with
QEXPECT_FAIL to document the failure in our truncation logic in
QTranslator.
The attempted fix in 9a11273b745a30cebb5cd648c89eb224e9704492 then
introduced QTBUG-129434, as we ignored the order of languages reported
by the system locale. Add a test case for that, and use a QSystemLocale
subclass inspired by the QLocale unit test to override the system locale
with a specific one that supports multiple languages for this test.
