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.

+      wavrsocvt is a command-line utility which can be used from a
+      terminal window or script to convert .wav files into sound
+      files for the NXT brick (.rso files). It can also convert the
+      other direction (i.e., .rso -> .wav). It can produce RSO files
+      with a sample rate between 2000 and 16000 (the min/max range of
+      supported sample rates in the standard NXT firmware).
+      You can then upload these with e.g. nxt-python.
