avcodec/bink: Don't waste space for VLC table
The Bink video decoder uses VLCs; the longest codes of these VLCs have different lengths, yet they are all so small that each VLC is read in one go, so that the number of elements in the VLC table actually used by each table is 1 << nb_bits, where nb_bits is the length of the longest code. Yet when determining the size of the VLC table nb_bits has been overestimated as the number of bits of the longest code in all VLCs, making said table unnecessary big (2048 vs 976 elements).
