Make windeployqt invocation work on latest Qt

--no-declarative and --no-winextras are no more recognised.

It went unnoticed when releasing 0.0.96 because windeployqt failures
caused CMake warnings rather than fatal stops. This has changed now:
from now on, installation on Windows will fail if windeployqt fails.
