The properties example for system properties did not work as expected

Renamed variable systemPropertiesProp to systemProjectProp in gradle.properties to match the idea of overridden properties and the given command line parameters. Now removing -Dorg.gradle.project.systemProjectProp=systemPropertyValue from the command line gives the expected result of the fallback to the gradle.properties variable.
