Disable chromevox time widget and date widget tests.

These are deprecated test suites and they conflict with the blink feature
to disable dispatching the default action on untrusted events.

Disable them since this code will eventually be removed when chromevox2
moves from beta to stable and it is not worth spending time fixing them.
