systemd: add support for executing scripts under /etc/rcS.d
This patch adds support for systemd to execute scripts under /etc/rcS.d. To be compitable, all services translated from /etc/rcS.d/ scripts would run before services translated from /etc/rcN.d scripts. [YOCTO #5159] Signed-off-by: Chen Qi <Qi.Chen@windriver.com>
