validate: launcher: Introduce new parameter for log file redirecting

Allow log file redirection through the new --redirect-logs parameter.
Keep the old --logs-dir stdout/stderr parameter, but reset to the
default logs directory in that case, and set redirect_logs internally.
This also prevents the creation of an stdout/stderr directory for
writing xunit.xml.
