php72-opcache-7.2.31: copying /usr/pkg/share/examples/php/opcache.ini to /usr/pkg/etc/php.d/opcache.ini

By default, example module configuration file was copied to following
location, and module should be auto-loaded:
/usr/pkg/etc/php.d/opcache.ini

If you use custom /usr/pkg/etc/php.ini, or nonstandard module
configuration file location, you might need to add explicit load directive:
zend_extension=/usr/pkg/lib/php/20170718/opcache.so
