[SPARK-29672][BUILD][PYTHON][FOLLOW-UP] Recover PySpark via pip installation with deprecated Python 2, 3.4 and 3.5

### What changes were proposed in this pull request?

The RC fails to install against Python 2.7 via `pip`. We deprecated but didn't remove Python 2, 3.4 and 3.5 support yet. This PR partially reverts the changes from SPARK-29672 to recover Python 2, 3.4 and 3.5 pip installation.

```bash
python2.7 -m pip install https://dist.apache.org/repos/dist/dev/spark/v3.0.0-rc1-bin/pyspark-3.0.0.tar.gz
```

### Why are the changes needed?

To keep the deprecated support instead of removing.

### Does this PR introduce any user-facing change?

No, it's the change in unreleased branches only yet.

### How was this patch tested?

```bash
./build/mvn -DskipTests -Phive -Phive-thriftserver clean package
cd python
python2.7 setup.py sdist
python2.7 -m pip install dist/pyspark-3.1.0.dev0.tar.gz
```
