    PR11151: Recover stap_uprobes slots on process exit
    
    When a process exits, it won't necessarily bother to munmap all of its
    shared libraries.  This patch makes sure that with uprobes in libraries,
    we still grab an exit notification and clear everything out.
    
    * runtime/uprobes-common.c (stap_uprobe_process_munmap): New.
    * tapsets.cxx (uprobe_derived_probe_group::emit_module_decls): Use above
      callback so that we can recover our resources on process exit.
