Now that I look closer, this patch illustrates one of the issues with
the pattern of virDomainCapsFeaturesInitUnsupported : that function is
used in the bhyve driver, but this patch doesn't update the bhyve test
suite domcaps output. devs can't add a new domcaps feature without
having to regenerate test output for every driver, which is a pain and
easy to overlook.

Thanks,
Cole
