Fix PHP-FPM monitor for EL /etc/php.ini

* Note: Map the shared EL PHP configuration file /etc/php.ini to the php-fpm boot action when that service exists, so the PHP-FPM status monitor can resolve current status on Rocky/RHEL systems.

root@rocky9-pro:~# php-fpm -i | grep "Loaded Configuration File"
Loaded Configuration File => /etc/php.ini
