Summary [Qt][WK2] WebKitTestRunner is dead

Poor WTR is always crashing on termination. This is a regression since r71409. The killer is me. In r71409 I haved connected the QSharedMemory object's deleteLater slot to QCoreApplication::aboutToQuit to force deletion when the SharedMemory is leaking on termination. The unsafeness of this approach is appearing when the SharedMemory's dtor is called after aboutToQuit had been emitted. In that case we are trying to delete an already deleted object and ending up in a crash. This is the situation in WTR when the UI process is terminating. (Ok, it is not really a UI process).
