Fix bdist_wheel

Without this, I get:

```
$ python setup.py bdist_wheel
...
copying ./library/cloud/azure ->
build/bdist.macosx-10.4-x86_64/wheel/private/tmp/ansible.venv/bin/../share/ansible/cloud
error:
build/bdist.macosx-10.4-x86_64/wheel/private/tmp/ansible.venv/bin/../share/ansible/cloud:
No such file or directory
```
