[OE-core] [PATCH 2/2] busybox: Add syslog-init alternative only if SysV in enabled

[Shakeel, Muhammad]

From: Muhammad Shakeel <muhammad_shakeel at mentor.com>

If systemd is enabled then syslog is handled through a service file
and related files in /etc/init.d are removed. This removes following
warning:

WARNING: busybox: NOT adding alternative provide /etc/init.d/syslog:
/etc/init.d/syslog.busybox does not exist
