[jdk23] RFR: 8335966: Remove incorrect problem listing of java/lang/instrument/NativeMethodPrefixAgent.java in ProblemList-Virtual.txt

[Jaikiran Pai]

I would like to backport this test-only change into `jdk23`. This cleans up the incorrect problem listing that was caused by a change that we introduced in JDK 23 as part of https://bugs.openjdk.org/browse/JDK-8333130.

This is a clean backport of the commit that was integrated into master branch through https://github.com/openjdk/jdk/pull/20094.
