mpegvideo: increase edge_emu_buffer size for VC1
The VC1 decoder uses edge_emu_buffer simultaneously for luma and chroma
and needs more space. That was not a problem before f1d8763a02b5fce
since the size for edge_emu_buffer was always calculated with 2 byte per
pixel since the linesize was not known.
Fixes occasionally fate errors in vc1_sa10143.
