add PHP_PGO_ALWAYS='n' variable in 123.09beta01

for PHP 7+ installs, setting PHP_PGO='y' will enable Profile Guided Optimizations for 5-25% better PHP performance but it takes longer for PHP to compile so by default PHP_PGO only enables if you have more than 2 cpu threads on server detected. If your server has 1 cpu core, then PHP_PGO is auto disabled even if you try to enable it. But this update adds a variable PHP_PGO_ALWAYS='n' by default which when set to PHP_PGO_ALWAYS='y' in persistent config file /etc/centminmod/custom_config.inc will override and enable PHP_PGO enable when PHP_PGO='y' set for 1 cpu thread servers too. PHP compiles times can be between 60-90% slower on 1 cpu core servers as PHP compile times depend on how many cpu cores and clock speed of those cpu cores. More cpu cores that are high cpu clock speed = faster PHP compile times.
