Currently, adding a package which is required either for development or testing requires it to be added in multiple places due to many duplicated Dockerfiles and installation scripts. This makes it difficult to ensure that all scripts are updated appropriately and can lead to some places being missed. This patch consolidates the list of dependencies and adds installation scripts for each package-manager used in our CI (apk, apt, dnf, pacman). This change also replaces the `debian/dev-packages.lst` as this subfolder conflicts with the Ubuntu/Debian packing scripts used for CRIU: https://github.com/rst0git/criu-deb-packages This patch also removes the CentOS 8 build scripts as it is EOL and the container registry is no longer available.
