Remove flaky keyboard layout test.

The current test is failing on cuttle fish devices and flaky on physical
devices:

1) settings_new_keyboard_ui needs to true for the test to pass. Flag override
requires device restart which we are not doing on cuttlefish devices.

2) virtual keyboard language/layout tags are set asynchronously by
   config change. This caused a race condition: the propogation of
   language tags can happen later then layout autoselection.

We will try adding the test back once the flakiness is fixed.
