valgrind: wildcard glibc version for dlopen() leak suppression

valgrind: wildcard glibc version for dlopen() leak suppression

the original suppression for "dlopen@@GLIBC_2.2.5" is very similar to
several later suppressions for "dlopen@@GLIBC_2.34". add a wildcard to
the original suppression so the rest can be removed

this also helps suppress a new leak, seen with gcc-13:
{
   <insert_a_suppression_name_here>
   Memcheck:Leak
   match-leak-kinds: reachable
   fun:malloc
   fun:UnknownInlinedFun
