Fix for upgrading agents >=3.10 by using API or agent_upgrade

Hi team,

This PR closes #3353. We were not checking Wazuh versions properly and it was impossible to upgrade agents to Wazuh 3.10 by using Wazuh API or agent_upgrade. Comparison between versions was made by lexicographical order and it fails when a field has more than two digits (3.10, for example).

Best regards,

Demetrio.

    Below there are examples of agents upgrading after applying this fix:

    bash
# cat /etc/ossec-init.conf 
DIRECTORY="/var/ossec"
NAME="Wazuh"
VERSION="v3.5.0"
REVISION="3510"
DATE="Thu Aug  9 19:13:23 UTC 2018"
TYPE="agent"

    `

    bash
# /var/ossec/bin/agent_upgrade -a 003 -v v3.6.0
Sending WPK: [=========================] 100%   
Upgrade procedure started... Please wait.
Agent upgraded: Wazuh v3.5.0 -> Wazuh v3.6.0

    bash
# cat /etc/ossec-init.conf
