Remove the timestamp from the user.properties template

This template, as used in the [sumologic_collector provider](https://github.com/SumoLogic/sumologic-collector-chef-cookbook/blob/master/providers/default.rb#L47),
triggers a restart notification. The presence of a timestamp means the file
content changes and a new restart notification is sent for every Chef run.
