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.

+      LittleGPTracker (a.k.a 'The piggy', 'lgpt') is a music tracker optimised
+      to run on portable game consoles. It is currently running on Game Park's
+      GP2x & Caanoo, PSP, Dingoo, Windows, Mac OSX (intel/ppc) & Linux (Debian).
+
+      It implements the user interface of littlesounddj, a very famous tracker
+      for the Gameboy platform that has been tried and tested by many users over
+      the years, leading to a little complex but yet extremely efficent way of
+      working.
+
+      Piggy currently supports 8 monophonic 16Bit/44.1Khz stereo sample playback
+      channels. Additionally, the program can drive MIDI instruments (with the
+      gp32 and gp2x a custom MIDI interface is required).
