template: simplify with forAllSystems and inline module

Browse source 
Use the forAllSystems pattern to reduce duplication and inline the
NixOS module directly in nixosSystem call. This eliminates the need for
separate nixosModules and nixosConfigurations outputs, making the
template more concise and easier to understand.

Also use virtualisation.munix namespace for the option.
