* io.c (make_writeconv): unversal_newline converter is for reading.

  so, if the io is text mode and has ECONV_UNIVERSAL_NEWLINE_DECORATOR
  flag, use crlf_newline converter for writing.
  this change fixes the problem about the luck of CR up Kernel.p and
  Kernel.puts to stdout/stderr on Windows.
