Removes the dependency on the Unitary object class from Terra and instead uses the two_qubit_kak function directly to synthesis a 2-qubit unitary in terms of u3 and cx.

Summary

Removes dependence of Unitary object from quantum volume benchmark circuits as this will likely be renamed/changed in a future Terra PR.

Fixes the quantum volume circuit to use the two_qubit_kak decomposition directly to add a random SU4 in terms of u3 and cx gates.
