Add maven property scout.excludeTestCategories

Maven property scout.excludeTestCategories allows to set excluded JUnit
test categories.
This additional property is required as not all tests depend on
platform.test module and therefore test category class may not be
available. If a test category class is not available maven surefire
cannot load JUnit test category classes and will fail. In later surefire
releases this would generate only a warning.

In a future scout release these test categories will be replaced by
JUnit 5 tags and then the build may be simplified.
