Thanks for mentioning: removed this from commit message.

"print_suppressions" is disabled intentionally, to not spoil the output
of the test; "heap_profile" is also disabled in Tarantool, and it is
experimental, so I'm afraid introducing flaky failures when enable it.
If you can suggest particular flags to be enabled, feel free to share in
the second version of the series[1].
