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 the executable VM. You should probably not care
+      about this package (which represents a packaging detail) and have a
+      look at the pharo-vm-core package instead.
+
+      Please fill bug reports on http://bugs.pharo.org under the 'Ubuntu
+      packaging (ppa:pharo/stable)' project.
