Fix integration tests to run better on ARM (#5101) 

In order for the integration tests to run successfully on a dedicated ARM cluster, two small changes are necessary:

* We need to skip the multicluster test since this test uses two separate clusters (source and target)
* We need to properly uninstall the multicluster helm chart during cleanup.

With these changes, I was able to successfully run the integration tests on a dedicated ARM cluster.
