Allow package_provider fact to resolve on PE 3.x

PE 3.x emits a puppetversion fact in the format "3.x.x (Puppet Enterprise 3.x.x)". This fact causes an error when invoked on PE 3.x: Could not retrieve fact='package_provider', resolution='<anonymous>': Malformed version number string 3.8.1 (Puppet Enterprise 3.8.1

This fix has been tested on PE 3.8.2 and should work for PE 3.3, 3.7, and 3.8.
