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.

+      Libsndfile is a C library for reading and writing files containing
+      sampled sound (such as MS Windows WAV and the Apple/SGI AIFF format)
+      through one standard library interface.  It is released in source
+      code format under the GNU Lesser General Public License.
+
+      The library was written to compile and run on a Linux system but
+      should compile and run on just about any Unix (including macOS).
+      There are also pre-compiled binaries available for 32 and 64 bit
+      windows.
+
+      It was designed to handle both little-endian (such as WAV) and
+      big-endian (such as AIFF) data, and to compile and run correctly on
+      little-endian (such as Intel and DEC/Compaq Alpha) processor systems
+      as well as big-endian processor systems such as Motorola 68k, Power
+      PC, MIPS and SPARC.  Hopefully the design of the library will also
+      make it easy to extend for reading and writing new sound file
+      formats.
