Revert "Change permissions of root_dir"

This reverts commit 979454afea21c8338006b601dd4081efae1ba306.

Which is good, because by overriding the `mode` param we would have been
forcing people to use `>= 1.8.3`.

This has been fixed upstream by changing the default mode in
stankevich/puppet-python@83ae489. The problem now only affects puppet-python
1.8.3 which has the orginal commit stankevich/puppet-python@f3e3695.
