CI: Add workaround for unavailable dependencies
until Squeekboard has been ported to GTK4 or GTK4-layer-shell.
Without this change, apt build-dep .
cannot be used to install
the build-dependencies on Debian Testing.
For the build_deb
-CI-job the dependencies are installed from Debian Unstable; for the other CI-jobs cargo
already downloads the dependencies.
