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.

+        Alloy is a language for describing structures and a tool for exploring
+        them. An Alloy model is a collection of constraints that describes a set
+        of structures, e.g. all the possible security configurations of a web
+        application, or all the possible topologies of a switching network. The
+        Alloy Analyzer is a solver that takes the constraints of a model and
+        finds structures that satisfy them. Structures are displayed graphically,
+        and their appearance can be customized for the domain at hand.
