chromeos-init: improve kernel logging
Some messages were appearing in the kernel ring-buffer (as examined
by dmesg), but not in /var/log/messages. It turns out that rsyslogd
defaults to filtering messages read from /proc/kmsg, so that only
kernel messages are candidates for logging.
This default is bad for us, since init (upstart) logs to the kernel
ring buffer. Resolve the problem, by disabling rsyslogd's filtering
of these messages.
