Add run script for unsat cores track at SMT-COMP (#177)

Note: this was a last minute effort, so we do not use the portfolio build for
this track. This part for example:

https://github.com/CVC4/CVC4/blob/d43e5fb294d89ba69f7d2607a12c8700b7ec9345/src/main/command_executor_portfolio.cpp#L351-L355

Would have to change before we can enable use the portfolio build for unsat
cores in a competition build.
