Add qt5-qtbase-static to fix building kwayland on Fedora
The Qt5::XkbCommonSupport CMake target is used by kwayland and that
depends on libQt5XkbCommonSupport.a, which lives in qt5-qtbase-static.
The qt5-qtbase-devel package includes the CMake files for
Qt5XkbCommonSupport, but doesn't depend on the -static package.
