SERVER-87285 made the find command batch size configurable and added it to the config fuzzer. covered_index_sort_no_fetch_optimization.js, computed_projections.js, and index_bounds_pipe.js use cursor.firstBatch to compare results. When the find command batch size is less than these results, they fail because all the expected results aren't recovered in the first batch. To fix this, we should block these tests from running in the config fuzzer. 

Additionally, block sortk.js and sorth.js from the config fuzzer as when the batch size is small, the limit can't be satisfied.
