This sets RocksDB as the default storage backend for `stateVersion` >=
24.11. For previous `stateVersion`s, the structured data and blobs
remain on SQLite and the filesystem respectively.
This is closer to the suggested upstream configuration for fully local
storage.
This makes `justStaticExecutables` error if the produced store path
contains references to GHC. This is almost always erroneous and due to
the generated `Paths_*` module being imported. This helps prevent
`justStaticExecutables` from producing binaries with closure sizes in
the gigabytes.
