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.

+      A script to configure transparent encryption of sensitive files stored in
+      a Git repository. Files that you choose will be automatically encrypted
+      when you commit them, and automatically decrypted when you check them
+      out. The process will degrade gracefully, so even people without your
+      encryption password can safely commit changes to the repository's
+      non-encrypted files.
