Don't assume QLocale::codecForLocale always returns non-null

It may return null during program exit, due to QCoreGlobalData global
static already having been destroyed, or due to the codec name/mib being
unsupported by ICU. If that's the case, QTextStream needs to fall back
to Latin 1, like QString::toLocal8Bit and fromLocal8Bit already do.
