Fix build with newer QtWaylandScanner

Because of a shortcoming in upstream qtwaylandscanner and the cmake
macro we defered to the ecm macro which renames the output files
acoording to what qtwaylandscanner expects. However since this
was corrected in newer Qt this doesn't build anymore since
the tool now expects correctly named files.
