Fix CppProjectUpdater cancelAndWaitForFinished

The code was pushing an additional QFutureInterface through the whole
chain of functions, which was used for canceling. But since it was never
started (and never finished, and never used for reporting results),
calling waitForFinshed on it never had any effect with Qt5 and locks up
with Qt6.

Instead of using a separate QFutureInterface, use the actual QFuture
that is available and intended for it.
