Description

Link input method plugins (uim, ibus, fcitx, m17nlib, scim, and canna) with libmef.

Reason for Change

The uim, ibus, fcitx, m17nlib, scim, and canna plugins use ef_* functions from libmef (e.g. via im_convert_encoding() in inputmethod/im_common.h) but do not link against it, unlike kbd/skk/wnn/iiimf which have @LMEF@.

Inside mlterm this goes unnoticed because libmef is already loaded. However, mlconfig calls dlopen() on the plugins to query im_*_get_info() without libmef. When built with BIND_NOW (hardening=+all), the dlopen fails due to the unresolved symbol (ef_bytes_to_int), causing the plugins to silently disappear from mlconfig's input method list.

Impact

This change ensures that all input method plugins properly link against libmef, allowing mlconfig to load them correctly even under strict hardening flags (BIND_NOW).
