Re: [mediacapture-image] Ignore PTZ request if no PTZ camera (#246)

@youennf It does. Though just to clarify: there are no required _basic_ imageCapture constraints anymore in `getUserMedia`. They still exist in `advanced: []`, in `track.applyConstraints`, and other specs.

This should fall out naturally once we fix https://github.com/w3c/mediacapture-image/issues/256 to have the spec match current design intent (right now `pan: true` has _zero_ impact on fitness distance, which was clearly no-one's intent. The intent was clearly for it to have weight like all other constraints have, like e.g. `facingMode: "environment"`.

I personally don't think we need to go further than that.
