chore(cache.tvl.su): Raise cache priority to 50

The priority of binary caches is decided by the remotes in Nix (???),
and by default nix-serve (which is *very* slow) has a lower priority
than cache.nixos.org (which means that it will be preferred over the
faster cache for paths that exist on both).

To avoid this, override the hardcoded (????) priority by serving the
nix-cache-info response directly from nginx instead.
