Fix tst_QEventLoop::processEventsExcludeSocket test

The testcase always returns the expected result, independently of the
QEventLoop::ExcludeSocketNotifiers flag to processEvents.

In Qt4 the same test uses an intermediate QEventLoop and already runs
it before the QEventLoop::ExcludeSocketNotifiers:

  QEventLoop loop;
  // allow the TCP/IP stack time to loopback the data,
  //  so our socket is ready to read
  QTimer::singleShot(200, &loop, SLOT(quit()));
  loop.exec(QEventLoop::ExcludeSocketNotifiers);

This fixes and improves the test by connecting, processing and
checking the bytesWritten signal for the pending connection socket.

Put parentheses around "min" to prevent expansion as macro

If you write xxxx::min(), min() might be expanded as a macro on silly
environments that follow that poor practice (read: inclusion of
<windows.h> without NOMINMAX). However, if you write (min)() or
(xxx::min)(), it means the same but prevents the expansion as macro.
