BUG: pandas.read_parquet no longer accepting a file-like object
#### Code Sample, a copy-pastable example

```python
from io import BytesIO
import numpy as np
import pandas as pd
import pytest

def test_read_parquet_on_stream():
    stream = BytesIO()
    df = pd.DataFrame({'col1': [1, 2], 'col2': [3, 4]})
    df.to_parquet(stream)
    result = pd.read_parquet(stream)
    assert np.array_equal(result.values, df.values)
```

#### Problem description

The documentation of `pandas.read_parquet()` (see [1]) says 

> Parameters: path: str, path object or file-like object

It is quite handy to be able to use a stream as parameter. It used to work with pandas version 1.0.3, but causes the error below for pandas version 1.0.4.

#### Expected Output

I expect the test to pass silently, which it does when using `pandas == 1.0.3`. 

#### Output 

But for `pandas == 1.0.4`, the test case fails due to `stream` not being a path-like object:

#### Details

Besides pandas, my `requirements.txt` contains the following relevant dependencies:
```
pyarrow ~= 0.15.1
pytest ~= 5.3.5
pyyaml ~= 5.1.2
```

My Python versions are 3.6.10 and 3.7.7.
