RFR: 8210469: Missing doPriviledged block and permission for jdk.zipfs module

I would prefer the way Mandy suggests.

Furthermore, the imports in the test case can be condensed to:

import java.io.IOException;
import java.nio.file.FileSystem;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.spi.FileSystemProvider;
import java.util.Map;

import org.testng.annotations.AfterClass;
import org.testng.annotations.BeforeClass;
import org.testng.annotations.Test;

Other than that: reviewed ��
