MINOR: hlua: removing ambiguous lua_pushvalue with 0 index
In cd341d531, I added a FIXME comment because I noticed a
lua_pushvalue with 0 index, whereas lua doc states that 0 is never
an acceptable index.
After reviewing and testing the hlua_applet_http_send_response() code,
it turns out that this pushvalue is not even needed.
So it's safer to remove it as it could lead to undefined
behavior (since it is not supported by Lua API) and it grows lua stack
by 1 for no reason.
No backport needed.
