Tests: omit needless requires_rmq for tests that don't need RabbitMQ

[danielhollas]

I noticed that there are a lot of tests marked with requires_rmq pytest marker even though they run perfectly fine without RabbitMQ. That probably comes from a time before the presto command and before there was an option to have a profile without a broker.

Split from #7074

Test plan

Make sure that the tests-presto CI job passes.
