tinyproxy: explicitly flush logged messages
On Windows, output streams are buffered when redirected to a file, and
TerminateProcess() apparently doesn't trigger a flush. This left
test-http-proxy.t missing part of the last line when it cat'd proxy.log[1].
Flushing stderr is all that is needed (on py27 anyway). I originally flushed
stdout too, but that added additional output to the log:
$ cat proxy.log
