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
  +  Accept: $LOCALIP (localhost)\r (esc)
  +  Serving HTTP on 0.0.0.0 port 20810 ...\r (esc)
  +       connect to localhost:$HGPORT\r (esc)
     * - - [*] "GET http://localhost:$HGPORT/?cmd=capabilities HTTP/1.1" - - (glob)
  +       bye\r (esc)
  +       connect to localhost:$HGPORT\r (esc)
     * - - [*] "GET http://localhost:$HGPORT/?cmd=branchmap HTTP/1.1" - - x-hgproto-1:0.1 0.2 comp=*zlib,none,bzip2 (glob)
  +       bye\r (esc)

     * - - [*] "GET http://localhost:$HGPORT/?cmd=stream_out HTTP/1.1" - - x-hgproto-1:0.1 0.2 comp=*zlib,none,bzip2 (glob)
  +       bye\r (esc)
  +       connect to localhost:$HGPORT\r (esc)
