Disable Solaris 11 SMF service at the end of postinstall script

[DFolchA]

Wazuh version	Install type	Action performed	Platform
4.4.4	Agent	Install/Upgrade	Solaris 11

We need to disable the SMF service that launches the post-installation tasks in Solaris 11, to avoid errors in the service log, /var/svc/log/site-wazuh-install:default.log

These changes should replace this line in the current postinstall script:

Validation

• Install executes start directive of SMF service without errors
• After reboot the service should not start and no errors in the log
• Upgrade executes refresh directive of SMF service without errors
