CmbIpc: Remove workaround

since the bug still exists. However, we use waitForBytesWritten()
instead of QCoreApplication::processEvents() since this seems to be fine
(QAbstractSocket::waitForBytesWritten is not called on Windows).
The bug was:
1. Open a bigger project, like qtcreator.pro.
2. After 2 seconds, quit it.
==> The Qt Creator window is gone but the Qt Creator process waits
until the clangbackend process is finished.
