ClassDefinitionUtils doesn't compile with Java 11

[ebourg]

ClassDefinitionUtils.defineClass() uses the Unsafe.defineClass() method which was removed in Java 11:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project objenesis: Compilation failure
[ERROR] ~/objenesis/main/src/main/java/org/objenesis/instantiator/util/ClassDefinitionUtils.java:[100,54] cannot find symbol

Thanks. I'm aware of it. Should have filed it. I'm on it right now. If you have a PR for that, I'm listening.
