perf kvm: Fix subcommands on s390
With commiteca0fa28cd
("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.
