package/php-lua: add support for php >= 8.5

Our php package was recently update to 8.5 version [1] but this version
removed some old function like zend_exception_get_default() [2].
But php-lua still uses zend_exception_get_default().

Replace zend_exception_get_default() by zend_ce_exception as suggested
by php project.
