Partially disable test

[danmoseley]

Fixes#33148

Sometimes file enumeration does not return the special "." directory. On Windows 11 this is now happening far more often. Disabling this part on there. My assumption is that this is not high priority to investigate as any app can assume it's there.

The failures on Android lanes in runtime-staging are issued here and will be activeIssued in #59762
The System.Collections.Tests failure is because of #59488 and will have a temporary fix in the same PR.
Not sure why the iOS arm64 lane is timing out for just 5 suites... maybe just unlucky with the osx hosted pool machines
