acme: fix buffer overrun in xfidutfread() and xfidruneread(), cleanup
the utf8 buffers b1 where allocated from fbufalloc() which gives
us BUFSIZE bytes, but Xfid->count can be bigger than that. so just
emalloc() the requested number of bytes.
when converting from Runes to utf-8, we have to account for the
terminating '\0' byte snprint() places, so fix the maxrune number
calculation instead of using BUFSIZE+1 as buffer size.
