This flag has been deprecated since Qt 4.4, so remove it.
tst_QApplication had 2 nearly identical tests, one for testing the
QEventLoop::DeferredDeletion flag, and one to test sendPostedEvents()
with QEvent::DeferredDelete. The latter is the preferred way, so keep
that test, but remove the test for the obsoleted flag.
