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.

+      PackageKit is a system designed to make installing and updating software
+      on your computer easier. The primary design goal is to unify all the
+      software graphical tools used in different distributions, and use some of
+      the latest technology like PolicyKit. The actual nuts-and-bolts distro
+      tool (dnf, apt, etc) is used by PackageKit using compiled and scripted
+      helpers. PackageKit isn't meant to replace these tools, instead providing
+      a common set of abstractions that can be used by standard GUI and text
+      mode package managers.
