[OE-core] [oe-core][PATCH 1/2] defaultsetup.conf: enable select init manager

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

Introduce a new variable INIT_MANAGER and create 3 init-manager-*.inc
files to configure init manager settings. Available values of
INIT_MANAGER are sysvinit, systemd and mdev-busybox. 'sysvinit' is set
by default for compatibility.

[YOCTO #13031]
