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.

+      CLI Helpers is a Python package that makes it easy to perform common
+      tasks when building command-line apps. It's a helper library for
+      command-line interfaces.
+
+      Libraries like Click and Python Prompt Toolkit are amazing tools that
+      help you create quality apps. CLI Helpers complements these libraries by
+      wrapping up common tasks in simple interfaces.
+
+      CLI Helpers is not focused on your app's design pattern or framework --
+      you can use it on its own or in combination with other libraries. It's
+      lightweight and easy to extend.
+
+      What's included in CLI Helpers?
+
+      - Prettyprinting of tabular data with custom pre-processing
+      - [in progress] config file reading/writing
