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.

+      Foremost is a console program to recover files based on their headers,
+      footers, and internal data structures. Foremost can work on image files, such
+      as those generated by dd, Safeback, Encase, etc, or directly on a drive.
+      The headers and footers can be specified by a configuration file or you can
+      use command line switches to specify built-in file types. These built-in types
+      look at the data structures of a given file format allowing for a more
+      reliable and faster recovery.
