Interdependencies errors on CI

The job https://github.com/apache/nuttx/actions/runs/4993159615/jobs/8941973789?pr=9138#step:7:448 shows an error while refreshing the `arty_a7:netnsh` defconfig.

This very same error happens while trying to build the master branch (OS: f61dc72892, APPS: 70a4010635):
```
make -j distclean && ./tools/configure.sh arty_a7:netnsh

```

I couldn't find any recent change to the `Kconfig`s that define those symbols. My guess: CI's machine was not using `kconfiglib` and was updated recently.
