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.

+      '' The GNU plotutils package contains software for both programmers and
+         technical users.  Its centerpiece is libplot, a powerful C/C++
+         function library for exporting 2-D vector graphics in many file
+         formats, both vector and raster.  It can also do vector graphics
+         animations.
+
+         libplot is device-independent in the sense that its API (application
+         programming interface) does not depend on the type of graphics file
+         to be exported.
+
+         Besides libplot, the package contains command-line programs for
+         plotting scientific data.  Many of them use libplot to export
+         graphics.
