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.

+      ''There are a variety of C unit testing frameworks available however
+        many of them are fairly complex and require the latest compiler
+        technology.  Some development requires the use of old compilers which
+        makes it difficult to use some unit testing frameworks. In addition
+        many unit testing frameworks assume the code being tested is an
+        application or module that is targeted to the same platform that will
+        ultimately execute the test.  Because of this assumption many
+        frameworks require the inclusion of standard C library headers in the
+        code module being tested which may collide with the custom or
+        incomplete implementation of the C library utilized by the code under
+        test.
+
+        Cmocka only requires a test application is linked with the standard C
+        library which minimizes conflicts with standard C library headers.
+        Also, CMocka tries to avoid the use of some of the newer features of
+        C compilers.
+
+        This results in CMocka being a relatively small library that can be
+        used to test a variety of exotic code. If a developer wishes to
+        simply test an application with the latest compiler then other unit
+        testing frameworks may be preferable.
