[OE-core] [meta-poky][PATCH v5 1/3] poky.conf: make systemd as default init manager

[kai.kang at windriver.com]

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

Move configurations from local.conf.sample.extended to poky.conf to make
systemd as default init manager for poky. Introduce a new variable
'POKY_INIT_MANAGER' whose value should be either 'systemd' or 'sysvinit'
to configure the init manager setting.

For users who still want to use sysvinit, set in local.conf or any other
configure file with:

  POKY_INIT_MANAGER = "sysvinit"

And consider security perspective, keep musl with sysvinit for now.

[YOCTO #13031]
