testsuite: generalize hwloc valgrind suppression

Problem: t5000-valgrind.t fails on Debian 11 aarch64 bcause the
valgrind fails with the following suppression signature:

 {
    <insert_a_suppression_name_here>
    Memcheck:Leak
    match-leak-kinds: definite
    fun:malloc
    fun:realloc
    obj:/usr/lib/aarch64-linux-gnu/libhwloc.so.15.4.1
    obj:/usr/lib/aarch64-linux-gnu/libhwloc.so.15.4.1
    fun:hwloc_topology_load
    fun:init_topo_from_xml
    fun:rhwloc_xml_topology_load
    fun:rlist_from_hwloc
    fun:topo_create
    fun:mod_main
    fun:module_thread
    fun:start_thread
    fun:thread_start
 }

This fails because an existing suppression is too specific.

Generalize the existing expression to match this case as well.
