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.

+      SLIB is a portable library for the programming language Scheme.  It
+      provides a platform independent framework for using packages of Scheme
+      procedures and syntax.  As distributed, SLIB contains useful packages
+      for all Scheme implementations.  Its catalog can be transparently
+      extended to accommodate packages specific to a site, implementation,
+      user, or directory.
+
+      SLIB supports Bigloo, Chez, ELK 3.0, Gambit 4.0, Guile, JScheme, Kawa,
+      Larceny, MacScheme, MIT/GNU Scheme, Pocket Scheme, RScheme, scheme->C,
+      Scheme48, SCM, SCM Mac, scsh, sisc, Stk, T3.1, umb-scheme, and VSCM.
