Subject: redhat: Add QEMU 9.1 compat handling to the s390x machine types

JIRA: https://issues.redhat.com/browse/RHEL-52319

Upstream changed the amount of information that is migrated for
the S390 interrupt controller (FLIC), so we have to switch on
a compatibility property for older machine types.
