Windows: stty: 'standard input': Inappropriate ioctl for device

### General summary/comments (optional)

On Windows running `stack path` as a subprocess results in an error printed to `stderr`:
```
stty: 'standard input': Inappropriate ioctl for device
```

### Steps to reproduce

Running normally inside a powershell has no problems:

```
PS C:\Users\lehins> stack --no-terminal path --project-root
C:\sr\global-project
```

But when executed as a subprocess

```haskell
Prelude System.Process> import System.Process
Prelude System.Process> res <- readProcess "stack" ["--version"] ""
Prelude System.Process> putStr res
Version 2.2.0, Git revision b8f8ec203209fccb1a86b9e8705f16125845254b PRE-RELEASE x86_64 hpack-0.31.2
Prelude System.Process> _ <- readProcess "stack" ["path", "--project-root"] ""
stty: 'standard input': Inappropriate ioctl for device
Prelude System.Process> _ <- readProcess "stack" ["--no-terminal", "path", "--project-root"] ""
stty: 'standard input': Inappropriate ioctl for device
```

There should be no reason that `stack path` would require anything from `stdin`.

### Expected

No error printed to `stderr`

### Actual

Here is the version with `--verbose`:

```
Prelude System.Process> r <- readProcess "stack" ["--no-terminal", "--verbose", "path", "--project-root"] ""

### Stack version

This issue is present in the latest released version as well, since I observed it on AppVeyor as well as on a local version of Windows 7
```
PS C:\Users\lehins> stack --version
Version 2.2.0, Git revision b8f8ec203209fccb1a86b9e8705f16125845254b PRE-RELEASE x86_64 hpack-0.31.2
```

### Method of installation

* `stack update --git`
