package/sysvinit: don't start logging

Don't try to start logging from /etc/inittab because busybox installs a
S01logging script that handles that and can lead to duplicate logging
processes.
Let's handle the logging in each package that provides it since we can
get multiple variants in the future like syslog-ng that have different
initialization routines.
