avcodec/mpc8huff: Make some arrays unsigned to prevent overflow

mpc8_q4_syms is an array of int8_t that is initialized using
values not in the range of an int8_t and that is only accessed via
a pointer to uint8_t in ff_init_vlc_sparse. The latter applies to all
the other *_bits and *_syms tables in mpc8huff.h, so make them all
unsigned.
