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.

+      Libavif aims to be a friendly, portable C implementation of the
+      AV1 Image File Format. It is a work-in-progress, but can already
+      encode and decode all AOM supported YUV formats and bit depths
+      (with alpha). It also features an encoder and a decoder
+      (avifenc/avifdec).
