[PATCH 1/2] Cygwin: syscalls.cc: Make _get_osfhandle() return appropriate handle.

[Takashi Yano]

- Currently, _get_osfhandle() returns input handle for pty even for
  stdout and stdout. This patch fixes the issue. Also, setup_locale()
  is called to make sure the charset conversion works for output.
