RFR: 8330534: Update nsk/jdwp tests to use driver instead of othervm [v3]

[Leonid Mesnik]

> The jdwp tests use debugger and debugee. There is no goal to execute debugger part with all VM flags, they are needed to be used with debugee VM only.
> The change is all tests is to don't use System.exit() and use 'driver' instead of othervm.
> test/hotspot/jtreg/vmTestbase/nsk/share/jpda/DebugeeBinder.java
> is updated to correctly set classpath for debugee
