commit 8a0d7e94f683597b368f34cd3b78d71663e16919
Author: Kevin Marshall <kmarshall@chromium.org>

Fuchsia: Include system logs in runner output by default.

System logs are included by default, unless they are deliberately
switched off by using the --no-system-logs flag.

-v now turns on DEBUG level logging and enables verbose mode for SSH.
