Partial fixed bug #79649 (Altering disable_functions from module init corrupts memory)

In module startup stage, we should not initiliaze
EG(modified_ini_directives) as it use zend MM, the zend MM will be
restart at the end of modules startup stage,

by say "partial", because this issue still exists if altering ZEND_USER
inis, we should add a zend_ini_deactive at the end of modules startup
stage, but it brings some new cost, and I think no one would do things
like that
