vc1parse: workaround for simple/main codec_data being 5 bytes long

Browse source 
Sometimes the codec_data buffer for simple/main pushed by asfdemux is 5 bytes
instead of 4. When that happens, codec_data is still valid but it seems to have
one 0x00 trailing byte. Might be a bug in the demuxer, needs more investigation.
