Tests: fix proxy_unfinished.t failures with big buffers.
With newer systems it becomes common to use huge socket buffers, and
the "no proxy temp" test may unexpectedly fail because disk buffering will
not be used. To reduce this possibility, the "listen ... sndbuf=32k" was
added.
Additionally, regular expression was changed to silently allow full
responses.
