Remove spurious changed state on iam_policy module (#4381)

Due to a mixup of the group/role/user and policy names, policies with
the same name as the group/role/user they are attached to would never be
updated after creation. To fix that, we needed two changes to the logic
of policy comparison:

- Compare the new policy name to *all* matching policies, not just the
  first in lexicographical order
- Compare the new policy name to the matching ones, not to the IAM
  object the policy is attached to
