    libc: fix c*rtomb/mbrtoc*

    In 693f88c9da8d ("iconv_std: complete the //IGNORE support"), we
    more completely implemented //IGNORE, which changed the semantics of
    ci_discard_ilseq. DISCARD_ILSEQ semantics are supposed to match
    //IGNORE, so we really can't do much about that particular
    incompatibility.  This broke c*rtomb and mbrtoc* handling of invalid
    sequences, but it turns out they don't want DISCARD_ILSEQ semantics at
    all; they really want the subset that we call
    _CITRUS_ICONV_F_HIDE_INVALID.

    This restores the exact flow in iconv_std to precisely how it happened
    prior to 693f88c9da8d.
