Title: Use systemd instead of replacing init

Changed readme to follow the ArchWiki entry on Kexec. This method creates a systemd unit for kexec instead of replacing init.

I found that it was not possible to replace init while the system is running:
cp: cannot create regular file ‘/sbin/init’: Text file busy

Furthermore, this method is more robust, and will not be overwritten by systemd upgrades.
