pmu-chain-promotion from ubuntu_kvm_unit_tests fails on B/F/H/J arm64

With kvm-unit-test repo updated to e11a0e2f88 ("s390x: Fix integer literal in skey.c"), there are 6 failures reported in this test on ARM64 now.

1: pmu-chain-promotion: odd counter did not increment on overflow if disabled
2: pmu-chain-promotion: should have triggered an overflow on #0
3: pmu-chain-promotion: CHAIN counter #1 shouldn.t have incremented
4: pmu-chain-promotion: CHAIN counter enabled: CHAIN counter was incremented and overflow
5: pmu-chain-promotion: 32b->64b: CHAIN counter incremented and overflow
6: pmu-chain-promotion: overflow is expected on counter 0
