The varnish tools (varnishstat, varnishlog, ...) tried to load the VSM file from a spurious var directory in the Nix store. Fix the default so the tools "just work" when also keeping services.varnish.stateDir at the default. Notes: - The tools use $localstatedir/$HOSTNAME so I've adapted the default for stateDir as well to contain hostName. - Added postStop action to remove the localstatedir. There is no point in keeping it around when varnish does not run, as it regenerates it on startup anyway. Fixes #7495
