audio/faad: Update to 2.11.2
Remove unneeded post-patch hack that was introduced in [1] to fix now
defunct multimedia/libquicktime. FAAD2_VERSION can be set to a proper
value by including <faad.h> if really neccesary, but the recommended
way to get the version string is to use the NeAACDecGetVersion() method,
which has been part of the API for over 8 years.
