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.

+    The Kythe project was founded to provide and support tools and standards

+      code. At a high level, the main goal of Kythe is to provide a standard,
+      language-agnostic interchange mechanism, allowing tools that operate on
+      source code — including build systems, compilers, interpreters, static
+      analyses, editors, code-review applications, and more — to share
+      information with each other smoothly.  '';
