Fix some style issues in Puppet manifests

These checks are performed on the Puppet Forge to give quality scores to
modules, and are failing for the choria repositories:
* The `ensure` parameter must be the first one in resource declaration;
* Non-interpolated strings should be single, not double-quoted.

While these changes are gratuitous, they will allow the scoring of the
modules to increase, giving users a more positive view of the care taken
to maintain them.
