build: reduce nix cache miss. 

Each pkgs.buildGoModule create a .go-modules sub derivation that is equivalent
to the vendor directory (aka it is copied to vendor). Before we have a cache
miss because this sub derivation has another name but it is the same (comapared
with nix-diff) here we rename this sub derivation to hit the network only once.

before:
$ nix build .#all --dry-run
these 15 derivations will be built:
