Cygwin: pty: Add FreeConsole to destructor of pty slave.

Browse Source 
- When pseudo console is closed, all the processes attched to the
  pseudo console are terminated. This causes the problem reported
  in https://sourceware.org/pipermail/cygwin/2020-March/244046.html.
  This patch fixes the issue.
