Disable FrameworksNetTests

Ideally the module branch would be unbundled and contain no framework
code or framework tests. Start by disabling the tests (which are not run
in this branch anyway) as they depend on test utils that are updated in
the module projects, but cannot be kept in sync as the latest tests
verify platform behavior that does not exist in the module branch.
