uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead

https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      Wireguard network manager, written in rust, simplifies the setup of wireguard nodes,
+      identifies short connections between nodes residing in the same subnet,
+      identifies unreachable aka dead nodes and maintains the routes between all nodes automatically.
+      To achieve this, wireguard network manager needs to be running on each node.
