IMPALA-8363: Fix E2E start with impala_log_dir

This commit fixes the `CustomClusterTestSuite` to wait for the
correct number of executors when `impala_log_dir` is specified
in the test decorator.  Previously, the default value of 3
was always used, regardless of `cluster_size`.

Testing:

- Manual verification using tests/authorization/test_ranger.py
with custom `impala_log_dir` and `cluster_size` arguments.
Failed before changes, passed after changes

- Ran all original E2E tests
