    main: Turn on all messages when logging to journal
    
    Unless turned on with the G_MESSAGES_DEBUG env variable, the default
    log functions drop debug and info messages. While this behavior is
    reasonable when writing to the console, the journal's log viewer
    already filters messages by priority by default, so it makes more
    sense to log everything in that case, as we won't have to ask people
    to reproduce issues with debugging turned on.
