package/ffmpeg: Add Kodi patchset

In the past xbmc delivered its own ffmpeg source code with specific patches to
address bugs found during the use of xbmc. For Helix the ffmpeg source code was
removed, Helix uses a vanilla ffmpeg source tarball and applies this patchset
on top of it.

+Subject: [PATCH 13/13] add public version of ff_read_frame_flush
+
+We need this since we sometimes seek on the
+input stream behind ffmpeg's back. After this
+all data need to be flushed completely.
+
+Patch part of the XBMC patch set for ffmpeg, downloaded from
