build_tools/rocksdb-lego-determinator to pass parallelism information for no_compression (#9796)

Summary:
Right now, parallelism information passed to "build_tools/rocksdb-lego-determinator no_compression" isn't effective when the test actually runs, as the information is dropped in the middle. Fix it.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/9796

Test Plan: Run "build_tools/rocksdb-lego-determinator no_compression" and execute the command line generated and observe the parallelism.
