When building kimchi's RPM, some messages are getting logged in /var/log/messages because cherrypy is logging in the standard output. This happens because a function in FeatureTests is enabling log.screen regardless of the current environment. This patch makes a verification that prevents the screen log to be enabled in the production environment.
