tests: Don't depend on kvm for tar and qcow2 tests

Some test runners don't have nested virtualization enabled. Because
these checks are only checking that a boot works, kvm doesn't give us
that much. Disable for now.

Also remove the check for qemu-kvm. It doesn't abort the test
prematurely anyway.
