[php-src] Issue #13915: Invalid nameserver delays php-cli execution

Issue: https://github.com/php/php-src/issues/13915 Author: nasu-wasabi ### Description The following code: ```php <?php echo "Hello World"; ``` Execute code: ``` php test.php ``` Resulted in this output: ``` Hello World ``` This is displayed correctly. However, there is a delay of about 60 seconds between execution and display. Delays occur when there is an invalid nameserver in resolv.conf as shown below. Occurs with this pattern: ``` cat /etc/resolv.conf nameserver <invalid nameserver> ``` Or this: ``` cat /etc/resolv.conf nameserver <invalid nameserver> nameserver <valid nameserver> ``` Does not occur if all nameservers are correct or none are defined. ### PHP Version PHP 8.4.3 or 8.2.17 or 7.4.33 ### Operating System Debian 12.5 or 11.9
