[SUREFIRE-2254] Ability to disable system-out/err for skipped tests in XML report

**[Stamatis Zampetakis](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=zabetak)** opened **[SUREFIRE-2254](https://issues.apache.org/jira/browse/SUREFIRE-2254?redirect=false)** and commented

The plugin always includes system-out and system-err in the XML report when a test is skipped. Developers treat a skipped test more or less the same with a successful test thus storing system-out and system-err is rarely useful.

Similar to SUREFIRE-1934, it would be convenient to have a property to disable system-out and system-err for skipped tests.

Start by reading the SUREFIRE-1934 issue and tracing the Surefire XML report handling for skipped tests. Identify the existing system-out/system-err configuration and its related tests; done means a property can suppress both elements for skipped tests without changing other report behavior.
