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.

+      '' Tokyo Cabinet is a library of routines for managing a database. The
+         database is a simple data file containing records, each is a pair of
+         a key and a value.  Every key and value is serial bytes with
+         variable length.  Both binary data and character string can be used
+         as a key and a value.  There is neither concept of data tables nor
+         data types.  Records are organized in hash table, B+ tree, or
+         fixed-length array.
+
+         Tokyo Cabinet is developed as the successor of GDBM and QDBM on the
+         following purposes.  They are achieved and Tokyo Cabinet replaces
+         conventional DBM products: improves space efficiency, improves time
+         efficiency, improves parallelism, improves usability, improves
+         robustness, supports 64-bit architecture.
