perf kvm: Fix subcommands on s390
With commit eca0fa28cd0d ("perf record: Provide detailed information on
s390 CPU") s390 platform provides detailed type/model/capacity
information in the CPU identifier string instead of just "IBM/S390".
This breaks 'perf kvm' support which uses hard coded string IBM/S390 to
compare with the CPU identifier string. Fix this by changing the
comparison.
