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.

+      xbanish hides the mouse cursor when you start typing, and shows it again when
+      the mouse cursor moves or a mouse button is pressed.  This is similar to
+      xterm's pointerMode setting, but xbanish works globally in the X11 session.
+
+      unclutter's -keystroke mode is supposed to do this, but it's broken[0].  I
+      looked into fixing it, but the unclutter source code is terrible, so I wrote
+      xbanish.
+
+      The name comes from ratpoison's "banish" command that sends the cursor to the
+      corner of the screen.
