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.

+      TestDisk is a powerful free data recovery software. It was primarily
+      designed to help recover lost partitions and/or make non-booting disks
+      bootable again when these symptoms are caused by faulty software: certain
+      types of viruses or human error (such as accidentally deleting a
+      Partition Table).
+
+      PhotoRec is a file data recovery software designed to recover lost files
+      including video, documents and archives from hard disks, CD-ROMs, and
+      lost pictures (thus the Photo Recovery name) from digital camera memory.
+      PhotoRec ignores the file system and goes after the underlying data, so
+      it will still work even if your media's file system has been severely
+      damaged or reformatted.
