[FLINK-8385] Fix exceptions in AbstractEventTimeWindowCheckpointingITCase
## What is the purpose of the change
This change fixes two types of exceptions that I found when running
`AbstractEventTimeWindowCheckpointingITCase` in debug mode (see JIRA).
## Brief change log
- *As a temporary fix for the first mentioned exception, we catch the
`RejectedExecutionException` and execute the `Runnable` directly.*
- *Suppress expected `CancellationException` or `ExecutionException` when
closing snapshot future task.*
## Verifying this change
This change is already covered by
`AbstractEventTimeWindowCheckpointingITCase`. You should no longer see the
mentioned exceptions when running all concrete instances of the test.
