externalscripts path not matching between server and default attributes

[odyssey4me]

The Zabbix Server common recipe creates node['zabbix']['external_dir'], but the server's configuration template sets the external scripts path as ['zabbix']['server']['externalscriptspath'].

Either the server common recipe should use the server attribute, or the template should use the common attribute and the server attribute should be removed. I think option two is best, personally.
