Jelle Zijlstra d2469c0e89 fix type for itertools.product (#2129) ...

Fixes #1850.

The fix was already applied to Python 2, but the typevar-based solution there
leads to "cannot infer value of type variable" in mypy. I used the following
script to check:

```python
from itertools import product

reveal_type(product([1]))
reveal_type(product([1], ['x'], [False], [3.0], [(1,)], [('x',)], [{1}], [{1: 2}], repeat=5))
```
