Fixes Windows setup dependency bug
Fixes Windows setup dependency bug

Fixes bug: #1212385

The neutron project includes a setup hook that allows to dinamically
include setup dependencies.

Due to recent changes in the pbr project, the hook raises an exception
on Windows, which ends the setup process.

This fix solves the issue by adapting the hook to the recent pbr changes.
