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.

+      tmux is a terminal multiplexer, like e.g. screen, which gives you a
+      possibility to use multiple virtual terminal session within one real
+      terminal session. tmux-cssh (tmux-cluster-ssh) sets a comfortable and
+      easy to use functionality, clustering and synchronizing virtual
+      tmux-sessions, on top of tmux. No need for a x-server or x-forwarding.
+      tmux-cssh works just with tmux and in an low-level terminal-environment,
+      like most server do.
