778b4e8 introduced the feature of saving the slog file of the ag-solo. However generating a slog file was only introduced in the SDK by Agoric/agoric-sdk#3611, so solos from older SDK would never open the slog FIFO, and the solo would have been considered as never fully started, ultimately timing out and failing.
This change makes the solo slog optional, and conditionally pipes the streams to avoid failures.
