fix(gate): declare the motion gate's two exported checks

The motion gate test imports sharedFeedbackControlProblems and
disabledTransitionOwnershipProblems, and the script has exported both since
before this branch; the hand-written declaration file never said so, so
typecheck:test failed on the imports rather than on the gate.
