[kvm-unit-tests PATCH v1 4/4] arm64: split its-migrate-unmapped-collection into KVM and TCG variants

When running the test in TCG we are basically running on bare metal so
don't rely on having a particular kernel errata applied.

You might wonder why we handle this with a totally new test name
instead of adjusting the append as we have before? Well the
run_migration shell script uses eval "$@" which unwraps the -append
leading to any second parameter being split and leaving QEMU very
confused and the test hanging. This seemed simpler than re-writing all
the test running logic in something sane ;-)
