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.

+      Dyndnsc is a command line client for sending updates to Dynamic
+      DNS (DDNS, DynDNS) services.  It supports multiple protocols and
+      services, and it has native support for IPv6.  The configuration
+      file allows using foreign, but compatible services.  Dyndnsc
+      ships many different IP detection mechanisms, support for
+      configuring multiple services in one place and it has a daemon
+      mode for running unattended.  It has a plugin system to provide
+      external notification services.
