Issue is: https://github.com/dotnet/core-eng/issues/11507 -- @bartonjs can we disable the tests in the meantime?

[GrabYourPitchforks]

Engineering services said it'll be a few days until the CI issue is resolved. Since we can't leave CI on the floor for that long, I've opened a PR to skip these tests on NetFx.

We should leave this issue open once that PR goes through. That way we can use this same issue to track re-enabling the tests once the CI issue is fully resolved.

I'm assigning the issue to myself to track re-enabling the tests.
