lang/php83: Add non-default NOASLR option

In certain corner cases php-fpm is creating zombie processes specially
from 13.2-RELEASE onwards. The exact reason has not been pin-pointed but
it looks like disabling ASLR solves the problem. So add a non-default
option NOASLR to allow the user build without ASLR.

This patch will not go into lang/php80 but will go in lang/php81 and
lang/php82 after some more extensive tests.
