Description:
------------
When access a non exists file in builtin web server. with --enable-debug it report 
leaks. 

When send error page, It call php_output_deactivate() it disabled the sent_headers 
callback but it will emalloc default_content-type. then it leaks.

So I think set SG(sapi_headers).send_default_content_type to 0 temporary can avoid 
leaking.

Test script:
---------------
NONE

Expected result:
----------------
no leaks

Actual result:
--------------
