Subject: [PATCH] rocmPackages.clr: add $out/lib to libamdhip64.so's rpath

Working around clr internally dlopening itself by bare name without a path, which will fail if it's not on the global library search path.

Likely will introduce an upstream PR that avoids this unnecessary look up current so by its bare name dance.
