Use the new version z3

[Moorvan]

In the current version of z3 in use, a problem is encountered with "Overflow encountered when expanding vector" during solving, which can be seen: Z3Prover/z3#864

It seems fixed in new version of z3. However, when I changed to use the new version of z3 in smt-switch, I meet:

Undefined symbols for architecture arm64:

It seems that api does not match.
