[benchmark] Skip broken benchmark on 8 cores.

This change skips one specific benchmark on 8 cores that only passes on
30 cores. The benchmark hangs and does not complete when run on the
8-core node pool. The 30-core node pool has `c2-standard-30` nodes,
compared to `e2-standard-8` for the 8-core node pool.

With this change, all benchmarks on both node pools should be passing.
