Cygwin: pipe: Use ProcessHandleInformation if available.

- The commit b531d6b0 introduced temporary_query_hdl() which uses
  SystemHandleInformation. With this patch, ProcessHandleInformation
  rather than SystemHandleInformation is used if it is available.
  This request is faster, however, is only available since Windows 8,
  therefore, SystemHandleInformation is used for Windows Vista and 7
  as before.
