po: msgstr entries with unmatched %-format string

The problem of GnuPG key generation only for Japanese was reported: https://dev.gnupg.org/T3619
It is due to unmatched %-format in msgstr (in po/ja.po).
This kind of bug can cause DoS targetted to a specific locale. I think that msgfmt -c should check this, too.
