remove mvPodUidDir test
**What this PR does / why we need it**:
Removes a [HostCleanup] test which deleted the pod's uid directory and checked to see that the host was cleaned up. This test consistently failed on gci (COS) due to OS differences related to handling mounting (containerized on COS) and rm'ing files being accessed. See #44592 for more details.
