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.

+    longDescription = ''
+      pekwm is a window manager that once upon a time was based on the aewm++
+      window manager, but it has evolved enough that it no longer resembles
+      aewm++ at all. It has a much expanded feature-set, including window
+      grouping (similar to ion, pwm, or fluxbox), autoproperties, xinerama,
+      keygrabber that supports keychains, and much more.
+
+      - Lightweight and Unobtrusive, a window manager shouldn't be noticed.
+      - Very configurable, we all work and think in different ways.
+      - Automatic properties, for all the lazy people, make things appear as
+        they should when starting applications.
+      - Chainable Keygrabber, usability for everyone.
