Initialize align_price_count and match_price_count in

lzma_encoder_init.c. While we don't call
fill_distances_prices() and fill_align_prices() in
lzma_lzma_encoder_init(), we still need to initialize
these two variables so that the fill functions get
called in lzma_encoder_getoptimum.c in the beginning
of a stream.
