[OE-core] [PATCH 2/2] sysklogd: lower the ALTERNATIVE_PRIORITY in case of systemd

[Qi.Chen at windriver.com]

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

The sysklogd package hasn't got systemd support yet. So in case of
a systemd based system, the commands and corresponding configuration
files should have a lower priority than that of the busybox's syslogd
and klogd utilities. These two utilities from busybox have internal
systemd support if CONFIG_FEATURE_SYSTEMD is enabled. And that config
item is enabled by default.
