Some containers lack /dev/console, so when multi_log attempts to open

that device and write to it directly things can start going haywire.
Here we address this problem by sending console-bound output to stdout
and letting init take care of getting it to the console instead.
We already configure upstart with "console output", so we need only
change systemd to use "journal+console".
