the init.d file for debian is confused about its filename

host:/var/log/zabbix# service zabbix-agent
Usage: /etc/init.d/zabbix_agentd {start|stop|restart|force-reload}
host:/var/log/zabbix# less /etc/init.d/zabbix_agentd
/etc/init.d/zabbix_agentd: No such file or directory

Note that there are two problems with this output:

1. It the output includes an underscore _, but the service uses a -.
2. It includes a trailing d, but the service name does not.

The same first problem occurs for zabbix-server.

I've attached a patch (against .D........ ZBXNEXT-1667 added frontend changes to the Changelog) which should fix this.

The version I encountered this problem is older, but the code is still broken in current.

One could use $0 instead if calculating name, but at least some debian scripts like to do some gymnastics (to handle cases where sysv init systems are in play).
