Disable cts-verifier tests that VR Standalone headsets do not support.

Daydream standalone headsets do not support alarm clock, car dock
and screen pinning features and as a result we should disable these
tests from even showing up on cts-verifier.
For standalone headsets they have their uimode set to "vrheadset" and
the resource values-vrheadset is parsed for disabled tests.
