kvm: selftests: introduce aarch64_vcpu_setup
This allows aarch64 tests to run on more targets, such as the Arm
simulator that doesn't like KVM_ARM_TARGET_GENERIC_V8. And it also
allows aarch64 tests to provide vcpu features in struct kvm_vcpu_init.
Additionally it drops the unused memslot parameters.
