[PATCH v2 1/3] Cygwin: syscalls.cc: Make _get_osfhandle() return appropriate handle.

[Takashi Yano <takashi.yano@nifty.ne.jp>]

- 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.
