Description

Hi team,

This PR fixes the absolute path error found in ossec.conf on Debian systems.
Having eliminated the PREFIX compilation variable, it is necessary to indicate the path in which you are working in the scripts used in postinst, in order to avoid the configuration block being hardcoded.

Logs example

After the changes, now the saved absolute path is modified according to the installation path selected when creating the package:

...
<ossec_config>
  <localfile>
    <log_format>syslog</log_format>
    <location>/usr/share/wazuh/logs/active-responses.log</location>
  </localfile>
...

Tests
