Add Features expected in Lolliop and Kitkat Watch platform versions

We're missing in CTS verifier a few newly added features in API level 20 and 21.
Also added a new hidden feature to the list so that it does not complain.

Also made faketouch optional, which should have been the case since Android 4.1
