8312049: runtime/logging/ClassLoadUnloadTest can be improved

[cost0much]

Backporting JDK-8312049 that improves ClassLoadUnloadTest; already backported to JDK21. Original commit does not apply cleanly due to the options "-Xlog:class+load+cause" "-Xlog:class+load+cause+native" were not added until a later version, thus these cases are excluded. Additionally, some args in exec() were not added until a later version, thus they have been excluded.

Passes tier1 tests on Linux x86 and the test itself.
