g10: In the TOFU module, make strings easier to translate.

* g10/tofu.c: Remove dead code.
(time_ago_str): Simplify implementation since we only want the most
significant unit.
(format_conflict_msg_part1): Use ngettext.
(ask_about_binding): Likewise and only emit full sentences.
(show_statistics): Likewise.
