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.
