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.

+      Zsh is a UNIX command interpreter (shell) usable as an interactive login
+      shell and as a shell script command processor.  Of the standard shells,
+      zsh most closely resembles ksh but includes many enhancements.  Zsh has
+      command line editing, builtin spelling correction, programmable command
+      completion, shell functions (with autoloading), a history mechanism, and
+      a host of other features.
