bug in transliteration module loader

[Bruno Haible]

The transliteration module loader will always add a .so suffix even if
it is already present, because of an off-by-one error.
(trans->name[name_len - 1] is always = '\0'.)

	* iconv/gconv_trans.c (__gconv_translit_find): Don't set need_so to
	true if trans->name already ends in ".so".
