Change the `authd.pass` ownership and permissions after creating it via deployment variables

[s-ocando]

Wazuh version	Install type	Action performed	Platform
4.3.6	Agent	Install	CentOS 7

When authd.pass is created via deployment variables, it stays with the default ownership and permissions:

-rw-r--r--. 1 root  root     11 Aug 19 06:22 authd.pass 

We should change the ownership to root:wazuh and permissions to 640.

[root@linux-agent vagrant]# ll /var/ossec/etc/
