Enable syslog on boot

This enables the busybox syslog implementation, which logs to
/var/log/messages, on boot. This is very helpful for debugging
applications which write to syslog (e.g. NetworkManager)

syslog is being set up to log to shared memory (not to disk), so log is
lost 1) on reboot and 2) if the service is restarted. It can be read
with `logread`
