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.

+      NetHogs is a small 'net top' tool. Instead of breaking the traffic down
+      per protocol or per subnet, like most tools do, it groups bandwidth by
+      process. NetHogs does not rely on a special kernel module to be loaded.
+      If there's suddenly a lot of network traffic, you can fire up NetHogs
+      and immediately see which PID is causing this. This makes it easy to
+      identify programs that have gone wild and are suddenly taking up your
+      bandwidth.
