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

https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948

+      Junkie is a network sniffer like Tcpdump or Wireshark, but designed to
+      be easy to program and extend.
+
+      It comes with several command line tools to demonstrate this:
+      - a packet dumper;
+      - a nettop tool;
+      - a tool listing TLS certificates...
