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.

+      Pharo's goal is to deliver a clean, innovative, free open-source
+      Smalltalk-inspired environment. By providing a stable and small core
+      system, excellent dev tools, and maintained releases, Pharo is an
+      attractive platform to build and deploy mission critical applications.
+
+      This package provides a front-end for starting the virtual
+      machine. The command 'pharo-vm' automatically detects the type
+      of image and executes a suitable virtual machine: CogV3, Spur,
+      or Spur64. This makes it easy to open Pharo images because you
+      do not have to worry about which virtual machine variant is
+      required.
+
+      More about the Cog family of virtual machines:
