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.

+      ext4magic can recover/undelete files from ext3 or ext4 partitions
+      by retrieving file-information from the filesystem journal.
+
+      If the information in the journal are sufficient, ext4magic can
+      recover the most file types, with original filename, owner and group,
+      file mode bits and also the old atime/mtime stamps.
+
+      It's much more effective and works much better than extundelete.
