opkg: Use systemd service for first boot configuration

Currently opkg uses a script to configure packages during first time boot.
This script is present in rcS.d and when 'sysvinit' is disabled this
script doesn't execute. For systemd only distros this newly added service
will run the opkg configure during first boot only.
