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.

+      Pangolin is a lightweight portable rapid development library for managing
+      OpenGL display / interaction and abstracting video input. At its heart is
+      a simple OpenGl viewport manager which can help to modularise 3D
+      visualisation without adding to its complexity, and offers an advanced
+      but intuitive 3D navigation handler. Pangolin also provides a mechanism
+      for manipulating program variables through config files and ui
+      integration, and has a flexible real-time plotter for visualising
+      graphical data.
