IMPALA-10054: Fix flakiness in test_multiple_sort_run_bytes_limits
test_multiple_sort_run_bytes_limits seems to become flaky in
ubuntu-16.04-dockerised-tests. This flakiness may come from accuracy
change in query estimates, the mem_limit specified in the test does not
fit anymore, or query concurrency in mini cluster that may disturb
expected memory allocation. This patch remove the second test case of
test_multiple_sort_run_bytes_limits due to variability in several test
run in the past. It does not compromise the test itself because the
basic feature of sort_run_bytes_limit is still verifiable by the
remaining test cases. The assertion is also changed a bit to allow
easier debugging in case test regression occurs again in the future.
Testing:
- Run and pass test_sort.py
