When supported_policy_files gets set under python 3.7 [1], the regex '(.*)'
matches twice, once for the policy file name and once more for the empty string
that follows the policy file name. This is new behavior under python
3.7. [2]
This leads to the replacement string being written out twice resulting
in something like this: "nova_policy.yamlnova_".
This patch changes the regex to '(.+)' ensuring there is no match success
against the empty string.
