With commit eca0fa28cd0d ("perf record: Provide detailed information on s390 CPU")
s390 platform provides detailed type/model/capacitiy information
in the CPU indentifier 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.

information in the CPU identifier string instead of just "IBM/S390".
This breaks 'perf kvm' support which uses hard coded string IBM/S390 to
