pru-icss: revert part of the last change that moved rpmsg_lib.lib to base_libdir

As part of replacing hard-coded /lib with ${base_libdir}, rpmsg_lib.lib was
also mistakenly moved from ${libdir} to ${base_libdir}, which is incorrect
and breaks other recipes, when they try to link against this library from
${libdir}.
