[OE-core] [PATCH 1/1] busybox-syslog: respect /etc/syslog-startup.conf in systemd

[Qi.Chen at windriver.com]

From: Chen Qi <Qi.Chen at windriver.com>

Now we've used busybox-syslog as a replacement for systemd's syslog
service. Currently, there are two problems.

1. The configuration file, /etc/syslog-startup.conf, is ignored.
   This is really confusing, as we are used to the behaviour of
   changing the configuration in /etc/syslog-startup.conf for the
   syslog service. This is actually a weekly test case.
2. The /etc/init.d/syslog is installed, but it has no real usage in
   systemd based systems.

This patch solves the above two problems by changing the busybox-syslog.
service file to let the /etc/init.d/syslog script start syslog service.
The /etc/init.d/syslog file is actually a wrapper in this situation.
