DT_RUNPATH is only used to find the immediate dependencies of the executable or shared object containing the DT_RUNPATH entry: 1. Define link-test-modules-rpath-link if $(build-hardcoded-path-in-tests) is yes. 2. Use $(link-test-modules-rpath-link) in build-module-helper so that test modules can dlopen modules with DT_RUNPATH. 3. Add a test to show why link-test-modules-rpath-link is needed. This partially fixes BZ #28455.
