defaults files are not sourced in and therefore no additional commands can be run on startup and/or config options passed to the agent. This patch fixes it.

I often do stuff like normalize hostnames and programatically work out management interfaces for the agent to bind to. The RHEL package startup script can do this, eg

$ cat /etc/sysconfig/zabbix-agent
ifconfig mgmt | awk '/inet /

{gsub(/addr:/,"",$2); print "ListenIP="$2}

' > /etc/zabbix/agentd.conf.d/listen.conf
conf="/etc/zabbix/agentd.conf"
echo "Hostname="`hostname| tr 'A-Z' 'a-z'` > /etc/zabbix/agentd.conf.d/host.conf
