RFR: JDK-8314121: test tools/jpackage/share/RuntimePackageTest.java#id0 fails on RHEL8 [v2]

[Matthias Baesken]

> on some RHEL Linux 8.X machines , we run into errors in test tools/jpackage/share/RuntimePackageTest.java#id0 , error can be seen below.
> It looks like these errors occur when running the jtreg tests with higher concurrency, I did not see them when running just the single test.
> 
> When adding some test output , we see the 2 top install dirs below (1 is expected, not 2) :
> ./test/unpacked-rpm/opt
> ./test/unpacked-rpm/usr
> 
> error output :
> 
> java.lang.AssertionError: Expected [1]. Actual [2]: Check the package has 1 top installation directories
