Log the response length for static files in the docker server

Browse Source 
The access log took $body_bytes_sent from res.body, which stays empty
for a static file because it is sent by a content provider. Every file
was logged as 0 bytes. Use the Content-Length of the response instead,
and 0 for HEAD.
