Disable benchmark test

The test checks that Scala collections perform within 10x of Java collections.
That's not something we need to test for dotty. And because of the heavily
parallel execution of the tests it does not always hold. This is the second
time in a a month that this particular test failed on jenkins. I think we lost
enough cycles on it.
