Bug 511316

SUMMARY

`qmlimportscanner` is missing library `libduktape.so.207` in kf6-core24-sdk edge 6.9.2

STEPS TO REPRODUCE
1.  install kde-qt6-core24-sdk, kde-qt6-core24, kde-qt6-core24-sdk, kde-qt6-core24 on edge channel
2.  build following package with --desctructive-mode ( kde-neon-6 extensions would take stable channel by default AFAIK)

```
name: mytest
version: "daily"
grade: stable
base: core24

      /snap/kde-qt6-core24-sdk/current/usr/lib/qt6/libexec/qmlimportscanner
      false
```

OBSERVED RESULT

libduktape.so.207 is missing
