Allow stdin to be a closed fd

Browse Source 
Before this change, the following invocation would not work

```
$ http http://neverhttps.com <&-
```

The "<&-" at the end closes the stdin fd. Specifically, it would fail with

```
  ...
  File "/home/mgsloan/.local/lib/python3.6/site-packages/httpie/context.py", line 26, in Environment
    stdin_isatty = stdin.isatty()
AttributeError: 'NoneType' object has no attribute 'isatty'
```

This can occur when httpie is being programmatically invoked, and may
as well be supported.
