swupdate: config via conf.d folder

This is a followup for: 135d46bc1446b49971f8f153c3cc55c2fec1e52f

Adding the systemd service files and the init scripts back to this
repository resolves the circular dependencies between menuconfig and the
Yocto build-system.

In addition, the conf.d folder is now also supported for sysv init based
systems.
