Disable pylint import checks for distutils
Disable pylint import checks for distutils

Pylint complains about distutils import in virtualenv (tox):
https://github.com/PyCQA/pylint/issues/73
```
E: 22, 0: No name 'version' in module 'distutils' (no-name-in-module)
E: 22, 0: Unable to import 'distutils.version.StrictVersion' (import-error)
```

Add inline pylint disable for `no-name-in-module` and
`import-error` checks as workaround for this issue.
