fdo#75526: sdk: install URE library symlinks / import libs again

This is a bit involved because since the LinkTarget now creates the
instdir/sdk/lib/* files itself a Package cannot be used; so convert the
URE libraries to AutoInstall and add special handling for them to
gb_Helper_register_libraries_for_install to create the necessary links
in the "sdk" install-module.
