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.

+      Faircamp takes a directory on your disk - your Catalog - and from it
+      produces a fancy-looking (and technically simple and completely static)
+      website, which presents your music in a way similar to how popular
+      commercial service bandcamp does it.
+
+      You can upload the files faircamp generates to any webspace - no database
+      and no programming language support (PHP or such) is required. If your
+      webspace supports SSH access, faircamp can be configured to upload your
+      website for you automatically, otherwise you can use FTP or whichever
+      means you prefer to do that manually.
