Update real-time benchmark config after opcache became mandatory

https://wiki.php.net/rfc/make_opcache_required removed the --enable-opcache option, and this change creates a problem for the benchmark: the master branch (containing the RFC implementation) cannot use the deprecated options and config anymore, while earlier versions must still use them.

Therefore, the benchmark had to introduce the PHP_OPCACHE=2 config value (kocsismate/php-version-benchmarks@3455b34) to signal that opcache still has to be manually enabled. After the next benchmark run,  PHP_OPCACHE for the previous PHP version has to be switched back to "1".
