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.

+      GNU lightning is a library that generates assembly language code
+      at run-time; it is very fast, making it ideal for Just-In-Time
+      compilers, and it abstracts over the target CPU, as it exposes
+      to the clients a standardized RISC instruction set inspired by
+      the MIPS and SPARC chips.
