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.

+      apksigcopier is a tool for copying android APK signatures from a signed
+      APK to an unsigned one (in order to verify reproducible builds).
+      It can also be used to compare two APKs with different signatures.
+      Its command-line tool offers four operations:
+
+      * copy signatures directly from a signed to an unsigned APK
+      * extract signatures from a signed APK to a directory
+      * patch previously extracted signatures onto an unsigned APK
+      * compare two APKs with different signatures (requires apksigner)
