Do not push main binary into cachix cache
Do not push main binary into cachix cache

The new release v9 of the cachix-action now supports filtering pushed
derivations. We now exclude the main binary for the project. This
prevents from flooding the cache with built derivations from the
cri-o binaries, since we usually want to cache only its dependencies.
