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.

+       PARI/GP is a widely used computer algebra system designed for fast
+       computations in number theory (factorizations, algebraic number theory,
+       elliptic curves...), but also contains a large number of other useful
+       functions to compute with mathematical entities such as matrices,
+       polynomials, power series, algebraic numbers etc., and a lot of
+       transcendental functions. PARI is also available as a C library to allow
+       for faster computations.
+
+       Originally developed by Henri Cohen and his co-workers (Université
+       Bordeaux I, France), PARI is now under the GPL and maintained by Karim
+       Belabas with the help of many volunteer contributors.
+
+       - PARI is a C library, allowing fast computations.
+       - gp is an easy-to-use interactive shell giving access to the PARI
+         functions.
+       - GP is the name of gp's scripting language.
+       - gp2c, the GP-to-C compiler, combines the best of both worlds by
+         compiling GP scripts to the C language and transparently loading the
+         resulting functions into gp. (gp2c-compiled scripts will typically run
+         3 or 4 times faster.) gp2c currently only understands a subset of the
+         GP language.
