RFR: 7903756: jcstress: Skip debugging JVM options for sub-processes [v7]

[Jiří Vaněk]

> No longer passing any -agentlib to subprocesses, unless it is part of -jvmArgsPrepend, thus allowing to debug both jcstress itself or wrked vm as expected:
> 
> java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=*:5005  -jar tests-all/target/jcstress.jar -c 1 -jvmArgsPrepend "-agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=*:5006"
> 
> works.
