Use 960-transformation in libfaad2
Previously the (default) 1024-transformation was used for PCM output, although
DAB+ uses the 960-transformation. This lead to audio being slower and lower
than the original source.
In libfaad2 the 960-transformation can be enabled by using a carefully crafted
AudioSpecificConfig for initialization, which is carried out by this commit.
