php_sapi_name return srv in fastcgi mode

When running HHVM in FastCGI mode, the php_sapi_name is returning the value srv while it should return cgi-fcgi or fpm-fcgi. This is causing an issue with Magento and Turpentine not setting the header content type correctly.

HHVM currently just returns RuntimeOption::ExecutionMode, as seen in ext_std_options.cpp:887. This is only ever set to either "srv" or "cli", from program-functions.cpp:868.

And from is seen in the comment of set_execution_mode, the function is called before the config has been loaded... Any possibility to change the value later once the server.ini has been loaded and the hhvm.server.type value has been read?
