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.

+      APG (Automated Password Generator) is the tool set for random
+      password generation.
+
+      Standalone version
+
+        Generates some random words of required type and prints them
+        to standard output.
+
+      Network version
+
+        APG server: When client's request is arrived generates some
+        random words of predefined type and send them to client over
+        the network (according to RFC0972).
+
+        APG client: Sends the password generation request to the APG
+        server, wait for generated Passwords arrival and then prints
+        them to the standard output.
+
+     Advantages
+
+       * Built-in ANSI X9.17 RNG (Random Number Generator) (CAST/SHA1)
+       * Built-in password quality checking system (it has support for
+         Bloom filter for faster access)
+       * Two Password Generation Algorithms:
+           1. Pronounceable Password Generation Algorithm (according to
+              NIST FIPS 181)
+           2. Random Character Password Generation Algorithm with 35
+              configurable modes of operation
+       * Configurable password length parameters
+       * Configurable amount of generated passwords
+       * Ability to initialize RNG with user string
+       * Support for /dev/random
+       * Ability to crypt() generated passwords and print them as
+         additional output
+       * Special parameters to use APG in script
+       * Ability to log password generation requests for network version
+       * Ability to control APG service access using tcpd
+       * Ability to use password generation service from any type of box
+         (Mac, WinXX, etc.) that connected to network
+       * Ability to enforce remote users to use only allowed type of
+         password generation
