Update the build dependencies:
- drop library packages already pulled in by dev packages:
libqt6quick3dglslparser6, libqt6waylandclient6,
libqt6waylandcompositor6, and libqt6wlshellintegration6
- mark QML module packages as !nocheck, since they are used only when
running the tests: qml6-module-qtqml-workerscript,
qml6-module-qtquick, qml6-module-qtquick-controls,
qml6-module-qtquick-layouts, qml6-module-qtquick-templates, and
qml6-module-qtquick-window
- drop qt6-translations-l10n, not actually needed
- replace the runtime package qt6-wayland with qt6-wayland-dev
