libfaad2:/ Remove forked internal libfaad2 copy
git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@32741 b3059339-0415-0410-9bf9-f77b7e298cf2
Remove AAC/FAAD2 installation instructions.
There is nothing special about building and installing FAAD2, so there is
no longer a need to keep maintaining instructions for it.
