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.

+Subject: [PATCH 13/19] add rootprefix to lookup dir paths
+
+systemd does not longer use the UDEVLIBEXEC directory as root for
+discovery default udev rules. By adding `$out/lib` to the lookup paths
+we should again be able to discover the udev rules amongst other default
+files that I might have missed.
