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.

+      qGo is a Go Client based on Qt 5. It supports playing online at
+      IGS-compatible servers (including some special tweaks for WING and LGS,
+      also NNGS was reported to work) and locally against gnugo (or other
+      GTP-compliant engines). It also has rudimentary support for editing SGF
+      files and parital support for CyberORO/WBaduk, Tygem, Tom, and eWeiqi
+      (developers of these backends are currently inactive, everybody is welcome
+      to take them over).
+
+      Go is an ancient Chinese board game. It's called "圍棋(Wei Qi)" in
+      Chinese, "囲碁(Yi Go)" in Japanese, "바둑(Baduk)" in Korean.
