CMake: Fix -rpath-link dependencies take two

Browse Source 
The previous implementation would pick up static Qt deps of a
shared Qt library as packages to find, but packages are not
created for these static libraries in a shared Qt build.

For example Qt::BundledSpirv_Cross is a static helper lib
that is linked directly into ShaderTools shared lib and no CMake
package is created for it, so we shouldn't look for it.

Separate the code path to filter out private dependencies
of a shared library target that don't have packages.
