[lworld] Integrated: [lworld] Don't run TestMethodHandles.java with -Xcomp

[Tobias Hartmann]

`TestMethodHandles.java` is really slow with `-Xcomp` and constantly times out. I filed [JDK-8371149](https://bugs.openjdk.org/browse/JDK-8371149) to track this but let's just not run the test with `-Xcomp` for now.

Thanks,
Tobias
