systemd_230.bb: Set journal RuntimeMaxSize to 64M as default

Browse Source 
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.
