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 gawkextlib project provides several extension libraries for
+            gawk (GNU AWK), as well as libgawkextlib containing some APIs that
+            are useful for building gawk extension libraries. These libraries
+            enable gawk to process XML data, interact with a PostgreSQL
+            database, use the GD graphics library, and perform unlimited
+            precision MPFR calculations.
