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.

+      Spoofer is a new client-server system for Windows, MacOS, and
+      UNIX-like systems that periodically tests a network's ability to
+      both send and receive packets with forged source IP addresses
+      (spoofed packets). This can be used to produce reports and
+      visualizations to inform operators, response teams, and policy
+      analysts. The system measures different types of forged
+      addresses, including private and neighboring addresses.  The
+      test results allows to analyze characteristics of networks
+      deploying source address validation (e.g., network location,
+      business type).
