BUG/MINOR: http-ana: Set HTX_FL_PROXY_RESP flag if a server perform a redirect

It is important to not forget to specify the HTX resposne was internally
generated when a server perform a redirect. This information is used by the H1
multiplexer to choose the right connexion mode when the response is sent to the
client.

This patch must be backported to 2.1.
