cmake: Add ugly hack from meta-qt5 to prevent cmake trying to detect qt5

* cmake doesn't have dependency on qt4/qt5, so these tests usually fail
  but still can cause undeterministic results or build failures (when
  OE_QMAKE_PATH_EXTERNAL_HOST_BINS is undefined or native qmake removed
  while running the test in cmake)
