Fix the libpng url
Bump to the latest version of ffmpeg.

The config patch was removed because examining the configure files seems to
show that the options are properly added now. I also had no problem building
ffmpeg once I removed the patch.
Bump zlib

The version of zlib linked is no longer available. In addition the download
is now not available in bz2. Change the build script to use the latest.
