MAD Decoder: Correct length of iTunes MP3 files 

The total frames count in the iTunSMPB header is the encoded length, so
add the start and end padding to it for the decoder implementation,
which expects this variable to contain the total decodable length
including the start and end padding. Fixes gapless decoding of iTunes
files.
