RFR: 8276688: Remove JLinkReproducibleXXXTest from ProblemList.txt

[Jaikiran Pai]

Can I please get a review for this change which removes the `JLinkReproducibleTest` and `JLinkReproducible3Test` tests from the `ProblemList.txt`?

With the fix for https://bugs.openjdk.java.net/browse/JDK-8275509 now merged, I expect these tests to stop failing intermittently. I have run these tests on my Linux setup before and after the fix for JDK-8275509. Before the fix, these tests used to fail at least a few times in 50 runs each. After the fix for JDK-8275509, I've run these tests at least a 100 times each and haven't seen any failures.

Having said that, I think it would be good to have someone run these a few times on a linux-aarch64 system and windows too. I don't have access to such setups.
