branches/zip: innodb-index.test: Add more columns and rows, to ensure 

that row_merge_blocks() will have some work to do when
row_merge_block_t is shrunk to 8192 bytes.

Currently, this will cause a debug assertion failure, because
row_merge_cmp() is considering all columns, not just the unique ones.
