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.

+      xosview is a lightweight program that gathers information from your
+      operating system and displays it in graphical form. It attempts to show
+      you in a quick glance an overview of how your system resources are being
+      utilized.
+
+      It can be configured to be nothing more than a small strip showing a
+      couple of parameters on a desktop task bar. Or it can display dozens of
+      meters and rolling graphical charts over your entire screen.
+
+      Since xosview renders all graphics with core X11 drawing methods, you can
+      run it on one machine and display it on another. This works even if your
+      other host is an operating system not running an X server inside a
+      virtual machine running on a physically different host. If you can
+      connect to it on a network, then you can popup an xosview instance and
+      monitor what is going on.
