[php-src] Issue #9959: php-fpm Solaris port event mechanism is still broken after #66694

Issue: https://github.com/php/php-src/issues/9959 Author: psumbera ### Description My original testing here was wrong: https://github.com/php/php-src/pull/6913#issuecomment-831868732 The easy test case is: ``` php-fpm -F -e -O [15-Nov-2022 14:28:16] NOTICE: fpm is running, pid 2127 [15-Nov-2022 14:28:16] NOTICE: ready to handle connections ^C[15-Nov-2022 14:28:18] NOTICE: Terminating ... [15-Nov-2022 14:28:18] NOTICE: exiting, bye-bye! ``` Note now it just never ends after displaying "Terminating ..." The issue is that it needs re-register for new event as it was suggested there (above - to add call to fpm_event_port_add()). ### PHP Version PHP 8.1.12 ### Operating System Solaris 11.4
