Disable flaky unit test RoundRobinSubcompactionsAgainstPressureToken (

#13416)

Summary:
The test is [flaky](https://github.com/facebook/rocksdb/actions/runs/13417174378/job/37480755623?fbclid=IwZXh0bgNhZW0CMTEAAR2pj4E1ua6zMxz4FxnPAPLIz011t1ddjaWPbmFlldfSG7dZGjWGVy-mDkg_aem_40kU2iCmcN93WsmzLZxGsA) and my previous [fix](#13347) did not seem to work. It's likely a test set up issue and disable the test for now since RoundRobin compaction style is not used to reduce some test failure noise.
