[native] Fix TaskManagerTest.buildSpillDirectoryFailure

[spershin]

Description

There is a race in the test itself, which we fix here:

• taskManager_->cleanOldTasks() can be called before the Driver is destroyed.
• Since the Driver holds the Task, the Task is considered a zombie inside cleanOldTasks() and is NOT removed from the map.
• So, destructor of the Task is not called.
• Then we call waitForAllTasksToBeDeleted() which simply compares how many ctors and dtors we had called. They don't match.
• Test fails.

Thanks for the fix. Does it make sense to just extend the test from velox's OperatorTestBase and reuse the rich utilities there?

@tanjialiang This test fixes the use of TaskManager's cleanOldTasks(). TaskManager is not in Velox, so we cannot use rich utilities from Velox.
