Build kvm-unit-tests out of tree

It is possible to build kvm-unit-tests out-of-tree by running
`configure` from the destination. Makefiles are created there and
correctly compile.

Switch kvm-unit-tests to build OOT to align with other projects in
out repo. With this, all generated files are in out/.
