const?

No. The whole point of it is that it can be changed (unlike the one inside a
WebMediaConstraints, which is only changed inside the Blink create() methods).

(the class might have been called a MockConstraintBuilder rather than a
MockConstraintFactory, but I did not want to depart that far from previous
naming.)
