lang/php81: Runtime fix

- php modules while build with system pcre fails to run when using
  apache httpd and mod_php. So OPTIONIZE and add as a non-DEFAULT
  option. However to my knowledge and experience I haven't faced this
  with nginx and php-fpm yet. [1]
- There is another corner case with apache httpd and mod_php when run
  on 13.2-RELEASE or newer specially on versions where ASLR is by default
  turned on. All modules specialy opcache crashes httpd. So add a
  warning message to advise users to move into php-fpm. [2]

Thanks to brnrd@ for the patch. [2]
