tooling headers: Synchronize updated s390 kvm UAPI headers

The 35b3fde6203b ("KVM: s390: wire up bpb feature") was noticed by the
perf build process:

Warning: Kernel ABI header at 'tools/arch/s390/include/uapi/asm/kvm.h' differs from latest version at 'arch/s390/include/uapi/asm/kvm.h'

The changes in this cset don't cause or require changes in tools/perf/,
so just update the copy to silence the build warning.
