Skip test_dlopenPublicLibraries when vendor version < R

Original problem is already fixed at ag/7781138.
It is not applied to qt-release. For now, we are
working on R-release. It seems doesn't needed
to apply patch to qt-release. So, in mixed build
case, skip test_dlopenPublicLibraries when vendor
image version is less than R
