msginit: Fix encoding of second title line, part 1.

Reported by Matilin Torre <watilin@protonmail.com> in
<https://lists.gnu.org/archive/html/bug-gettext/2025-07/msg00024.html>.

* gettext-tools/src/msginit.c: Include xstriconv.h.
(get_title): Don't set OUTPUT_CHARSET; this does not work any more since 2005,
when an optimization was made in dcigettext.c. Instead, use xstr_iconv().
