InCallUI: Workaround for aapt warnings

Change-Id: I1b28aca47f69b5559152e7bc23371a54bd9a47e4
Don't expand the contact picture behind the call buttons during call.

Doing that avoids stretching more than needed. To avoid a visual 'jump'
of the contact picture when answering the call, animate the contact
picture layout transition.

Make incoming call screen style configurable. (2/3)

Avoid layout changes on call disconnection.

This avoids showing the call buttons when an incoming call is
disconnected remotely while still ringing, which in turn avoids an ugly
transition when using the full screen caller photo.
