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 gperf is a perfect hash function generator.  For a given
+      list of strings, it produces a hash function and hash table, in
+      form of C or C++ code, for looking up a value depending on the
+      input string.  The hash function is perfect, which means that
+      the hash table has no collisions, and the hash table lookup
+      needs a single string comparison only.
+
+      GNU gperf is highly customizable.  There are options for
+      generating C or C++ code, for emitting switch statements or
+      nested ifs instead of a hash table, and for tuning the algorithm
+      employed by gperf.
