[Bug 57087] mod_proxy_fcgi doesn't send cgi CONTENT_LENGTH variable when the client request used Transfer-Encoding:chunked

Today is typo-day, I used sendcl in my tests but typed in here 'ctl', sorry :(
I retried to be sure, same result.

I checked and indeed it is implemented only in _http, not _fcgi, but it is a
good pointer!

After reading a bit the code, I'd add a condition in mod_proxy_fcgi's
dispatch() to add the missing CL if TE:chunked is present, but I am not super
clear if it is possible to do such a thing from the data in request_req. It
seems to me that it shouldn't be super difficult but I need to read more code
before adding a meaningful code change. I'll try during the next days if
anybody doesn't beat me :)
