vmTestbase/nsk/jvmti/ResourceExhausted/resexhausted003 and 004 use wrong path to test classes

resexhausted003 uses ../../classes/0/vmTestbase as path to class files, which will work only if the test is run in 0th agent.
resexhausted004 uses ./bin/classes which doesn't exist at all.

the suggested fix is to use PropertyResolvingWrapper and ${test.class.path}
