dist/init/linux-sysvinit: caddy for SysVinit

dist/init/linux-sysvinit/README.md

+SysVinit conf for Caddy
+=======================
+
+Usage
+-----
+
+* Download the appropriate Caddy binary in `/usr/local/bin/caddy` or use `curl https://getcaddy.com | bash`.
+* Save the SysVinit config file in `/etc/init.d/caddy`.
+* Ensure that the folder `/etc/caddy` exists and that the subfolder `ssl` is owned by `www-data`.
+* Create a Caddyfile in `/etc/caddy/Caddyfile`
+* Now you can use `sudo /etc/init.d/caddy start|stop|restart|reload|status`.
