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 Dico is a flexible modular implementation of DICT server
+      (RFC 2229).  In contrast to another existing servers, it does
+      not depend on particular database format, instead it handles
+      database accesses using loadable modules.
+
+      The package includes several loadable modules for interfacing
+      with various database formats, among them a module for dict.org
+      databases and a module for transparently accessing Wikipedia or
+      Wiktionary sites as a dictionary database.
+
+      New modules can easily be written in C, Guile or Python.  The
+      module API is mature and well documented.
+
+      A web interface serving several databases is available.
+
+      The package also includes a console client program for querying
+      remote dictionary servers.
