kata-env: Fix display of debug options

The runtime and hypervisor `Debug` options were always showing as
`false` (although all debug options in `configuration.toml` were
correctly honoured).

Note: Also moved location of `FactoryConfig` in `RuntimeConfig` as the
`malign` linter was complaining:

```
virtcontainers/pkg/oci/utils.go:102:20:warning: struct of size 408 could be 400 (maligned)
```

Fixes #724.
