Subject: * process.c (redirect_dup2): set standard handles when new fd is
 stdio,   because if there is no allocated console at the moment Windows does 
  not automatically associate it for child process's standard handle.   this
 is adhoc workaround.   reported by Martin Thiede at [ruby-core:48542] [Bug
 #7239].

* io.c (rb_cloexec_dup2): ditto.
