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.

+      Oxygen Font is a font family originally aimed as a desktop/gui
+      font for integrated use with the KDE desktop.
+
+      The basic concept for Oxygen Font was to design a clear,
+      legible, sans serif, that would be rendered with Freetype on
+      Linux-based devices. In addition a bold weight, plus regular and
+      bold italics, and a monospace version will be made.
+
+      Oxygen is constructed closely with the gridfitting aspects of
+      the Freetype font rendering engine. The oxygen fonts are also
+      autohinted with Werner Lemberg's "ttfautohint" library to
+      further the compatibility with the Freetype engine. The aim of
+      this approach is to produce a family of freetype-specific
+      desktop fonts whose appearance will stay uniform under different
+      screen render settings, unlike more traditionally designed
+      'screen fonts' that have tended to be designed for best
+      legibility on the Windows GDI render engine.
+
+      The main creator of Oxygen, Vernon Adams, suffered a heavy
+      traffic accident three months after its last release, causing him severe brain
+      injury. He finally passed away, sans oxygen, on August 25th 2016.
