Test proxy_unfinished: limit sndbuf to force buffering on no proxy temp

With some systems (Fedora-20 Linux 3.13) socket buffers are huge and
nginx does not use temp files when proxying. Set sndbuf to small
values to make use of temp files around 90k sent. Currently there is
no way to force temp buffers. If sndbuf is more than 36k test seems to
fail.

no proxy temp should fail on 1.5.2 and work okay on later versions.

sub_filter forces chunked encoding and so it is possible to notice
problem because last chunk is 0 chunk when there is error.

http://trac.nginx.org/nginx/ticket/541

I did not notice any changes with sleep or limited proxy buffers.
So I dropped them.

Changed patch as per suggestion from Maxim Dounin.
