Since poky commit b6fbb3f3d4d6367b0fd7921078f67057551c7ede
reboot config was moved to init.cfg to provide this configuration
when busybox is selected as the init manager, however it is needed
for initramfs images where no init manager is set (see poky commit
ef4a417ab04779bd9fc8a6540a20cca7d14e98cf).
