deps: update ycsb dependencies

[olavloite]

Updates the JDBC driver and the Unix domain socket implementation dependencies that are used for running the YCSB benchmarks. Also increases the number of operations per test run, and removes the test runs with a batch size of 200, because:

1. Longer runs give a more realistic picture, especially for the Cloud Spanner JDBC driver, as less warm-up effect is seen in the execution times.
2. batch_size 200 did not affect the performance compared to other batch sizes, and the removing this run leaves us enough time to increase the operation count.
