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 Monkeysphere project's goal is to extend OpenPGP's web of
+      trust to new areas of the Internet to help us securely identify
+      servers we connect to, as well as each other while we work online.
+      The suite of Monkeysphere utilities provides a framework to
+      transparently leverage the web of trust for authentication of
+      TLS/SSL communications through the normal use of tools you are
+      familiar with, such as your web browser0 or secure shell.
