Bug description:Memory leak when access a non-exists file without router

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:
--------------
