Improve nix-store --delete failure message

On several occasions I've found myself confused when trying to delete
a store path, because I am told it's still alive, but
nix-store --query --roots doesn't show anything.  Let's save future
users this confusion by mentioning that a path might be alive due to
having referrers, not just roots.
