8312049: runtime/logging/ClassLoadUnloadTest can be improved

[cost0much]

Backport that improves ClassLoadUnloadTest; already backported to JDK21 and JDK17. 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. Some args in exec() also were not added until a later version, thus they are excluded. Additionally, these flags were deprecated in a later version and thus removed from this test; simple modifications are added so that these later removed cases follow the backport logic. Affected test passes.

MacOS GHA not passing due to unrelated deprecated sprintf
