cmd/dockerd: replace deprecated windows.IsAnInteractiveSession()

The `IsAnInteractiveSession` was deprecated, and `IsWindowsService` is marked
as the recommended replacement.

For details, see https://github.com/golang/sys/commit/280f808b4a5303f80a30dd9dc62f9a042d992ad0

> CL 244958 includes isWindowsService function that determines if a
> process is running as a service. The code of the function is based on
> public .Net implementation.
>
> IsAnInteractiveSession function implements similar functionality, but
> is based on an old Stackoverflow post., which is not as authoritative
> as code written by Microsoft for their official product.
>
> This change copies CL 244958 isWindowsService function into svc package
> and makes it public. The intention is that future users will prefer
> IsWindowsService to IsAnInteractiveSession.
