[SPARK-6219] [Build] Check that Python code compiles
This PR expands the Python lint checks so that they check for obvious
compilation errors in our Python code.
For example:
```
$ ./dev/lint-python
Python lint checks failed.
Compiling ./ec2/spark_ec2.py ...
File "./ec2/spark_ec2.py", line 618
return (master_nodes,, slave_nodes)
^
SyntaxError: invalid syntax
./ec2/spark_ec2.py:618:25: E231 missing whitespace after ','
./ec2/spark_ec2.py:1117:101: E501 line too long (102 > 100 characters)
```
This PR also bumps up the version of `pep8`. It ignores new types of checks
introduced by that version bump while fixing problems missed by the older
version of `pep8` we were using.
