CI: Ensure SOVERSION symlinks exist in created App Bundle

Bundles libraries are available via their specific versioned filename
as well as SOVERSION and versionless symlinks. Dylibbundler does _not_
include these symlinks when copying linked libraries into the bundle.

This change ensures that all libraries and their SOVERSION symlinks
exist in the created App Bundle.
