Make new regression indpendent of max_parallel_workers_per_gather.
The tests in
e2f1eb0ee30d1 ("Implement partition-wise
grouping/aggregation.") weren't independent of the server's
max_parallel_workers_per_gather setting. I (Andres) find it useful to
locally run with that disabled, and the aforementioned patch broke
this.
