wav: Demux cover art

[Kirill Danilenko]

Summary of the bug:

ffplay does not show cover picture in it's gui window. Attached file contains picture described by id3v2.2 tags. File is wav. From libavformat/utils.c I found that id3 parsing happens only with mp3, aac, tta formats. If add wav condition parsing done well. Is it correct to add wav id3 parsing functionality?

How to reproduce:
% ffplay test.wav
