    systemd_230.bb: Set journal RuntimeMaxSize to 64M as default
    
    At this time systemd journald uses the /run tmpfs to store logs
    by default systemd uses 15% of available space [1] of the /run
    partition, when the space runs out journald starts to vaccum/store
    the logs into /var/log [1].
    
    It causes two problems one of them is timeout dev-ttySN.device's
    when enable debug and use journal as systemd.log_target [2] the other
    is related to don't find syslog entries into the journal log [3].
    
    This problems are now more evident because i recently enabled the
    systemd debug option in testimage [4].
    
    One area of improvement will be add support in systemd journald to
    read these parameters from the kernel cmdline like systemd.log_target,
    if the support exists we could add that parameter at level of testimage.
