[libvirt] [PATCHv2 1/5] S390: Override QEMU_CAPS_NO_ACPI for s390x

Starting a KVM guest on s390 fails immediately. This is because "qemu --help" reports -no-acpi even for the s390(x) architecture but -no-acpi isn't supported there. Workaround is to remove QEMU_CAPS_NO_ACPI from the capability set after the version/capability extraction.
