fix mod_proxy_backend_http vulnerability

Description

If the http-backend sends back an invalid response, like:

HTTP/1.1 200 OK
...
Transfer-Encoding: chunked
...

\0\r\n
1111111111111111......

Of course, the chunk-length "\0" is not valid. However, lighttpd trapped into an endless loop at the monent. It cannot serve any more, and its cpu usage is up to 100%.

In this case, mod_proxy_backend_http should just stop, and return HANDLER_FINISHED.
