[jdk11u-dev] RFR: 8238268: Many SA tests are not running on OSX because they do not attempt to use sudo when available [v2]

[Christoph Langer]

> This is a backport of [JDK-8238268](https://bugs.openjdk.org/browse/JDK-8238268). We need it, because the backport of [JDK-8215544](https://bugs.openjdk.org/browse/JDK-8215544) has added code that calls `sudo -E` on MacOS without the option `-n`. This call might not return when sudo starts prompting for a password. In our CI it leads to hanging processes when subsequent tests call sudo, even with the -n option. This fix rectifies that behavior. And, after all, it improves test coverage on MacOS, so it's a good backport candidate.
