The [JDK-8314838](https://bugs.openjdk.org/browse/JDK-8314838) added support for additional forwarding of the JTReg javaoptions to the subprocesses, but broke the original arguments passing. They are now passed to the enclosing driver and simply ignored by ProcessTools.createTestJvm. As a result, proper compiler may be not chosen on subprocess start, etc. This PR fixes that.
