This is a followup to commit c803ffcb.

* gnu/packages/patches/icecat-libvpx-1.4.patch: Augment existing patch to
  include fixes for content/media/encoder/VP8TrackEncoder.cpp.

gnu/packages/patches/icecat-libvpx-1.4.patch

 The libvpx package 1.4.0 brings new names for various constants.
-To build against the libvpx some few constants have to be renamed.
 
-Patch by Carsten Schoenert <c.schoenert@t-online.de>.
-Copied from Debian.
+Based on a patch by Carsten Schoenert <c.schoenert@t-online.de>.
