make PHP_PGO='y' available on initial installs in 123.09beta01

- PHP_PGO='y' to date only enabled profile guided optimisations for PHP 7+ when 2 or more cpu cores/threads were detected for php upgrade routines via centmin.sh menu option 5. PHP_PGO='y' wasn't enabled for initial centmin mod 123.09beta01 installs. This update enables it for initial installs too when PHP_PGO='y' was set in persistent config file /etc/centminmod/custom_config.inc prior to running centmin mod 123.09beta01 with PHP 7.0, 7.1, 7.2 or 7.3 default installers.
- PHP_PGO='y' can increase the time it takes to compile PHP 7+ - can take 2-5x times longer to compile depending on speed of your server and how many cpu core/threads you have. But the resulting PHP 7 binaries can be between 5-25% faster for some PHP code paths and work loads from benchmarks https://community.centminmod.com/threads/php-7-3-vs-7-2-vs-7-1-vs-7-0-php-fpm-benchmarks.16090/.
