Send logs from the linelog module to stdout

Hi, I am running radiusd in Docker container. In configuration radiusd.conf I had set the user and group variable to drop permission after the start. Radiusd process is started with `-fl stdout` to redirect radiusd process logs to stdout and let Docker collect necessary logs. But in the linelog module if I will use /dev/stdout as filename radiusd seems can't open it for writing. Also, Docker requires `tty=true`, or permissions to /dev/stdout granted only to root. May I ask if there is an option that I am missing, to redirect linelog output to stdout? Best regards, Valdimir
