IMPALA-7708: Switch to faster deflater compression level for incr stats

On a table with 3000 partitions and ~150 columns, we noticed that the
BEST_SPEED deflater strategy is ~8x faster with ~4% compression ratio
penalty. Given these results, this patch switches the default to
BEST_SPEED from BEST_COMPRESSION.
