Summary:
It seems that an incorrect native source file entry was introduced in https://github.com/facebook/rocksdb/pull/8999. For some reason it appears that CI was not run against that PR, and so the problem was not detected.

This PR fixes the problem by removing the invalid entry, allowing RocksJava to build correctly again.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9147
