systemd: create /var/lib/systemd/backlight in advance

v2 changes:
* Update patch for Yocto Compat - don't change layer's hash

============================================

The systemd-backlight@.service which called after selinux-init.service
will create /var/lib/systemd/backlight with incorrect security labels,
this causes the systemd-backlight service fails to start and stop.

Creating /var/lib/systemd/backlight in advance to make sure it could
always be relabelled by selinux-init while first booting.
