Issue with ossec group in reinstall Wazuh agent 4.3.4 in Solaris 11 SPARC

[c-bordon]

I found a possible problem when trying to reinstall the agent on a Solaris 11 Sparc system, this occurs after having the agent installed, uninstalling it and reinstalling it without removing the wazuh group:

steps to replay it:

• install Wazuh agent (https://packages-dev.wazuh.com/pre-release/solaris/sparc/11/wazuh-agent_v4.3.4-sol11-sparc.p5p)

• We can see that group ossec is created:

root@sossp109:~# cat /etc/group | grep ossec                                  
ossec::11:

• After delete wazuh group the reinstallation was succeded:

root@sossp109:~# groupdel ossec
root@sossp109:~# pkg install -g wazuh-agent_v4.3.4-sol11-sparc.p5p wazuh-agent

I repeated the tests again but this time eliminating the wazuh group before trying the reinstall and there the reinstallation worked correctly, that is, in the reinstall process if the wazuh group exists it generates the ossec group
