[Yasumasa Suenaga]

> This PR is for redo-ing [JDK-8271949](https://bugs.openjdk.java.net/browse/JDK-8271949).
> I changed to use `SecuritySupport` at `Options::setDumpPath` as @egahlin mentioned. Please see change both Options.java and SecuritySupport.java .
> 
> I've tested this change with all jdk/jfr tests on Linux x64, and they works fine.
> @egahlin @mgronlun Can you run Mach5 tests with this change?
