    PR14244: Assert that the real UID has access to debugfs
    
    Some systems are now defaulting debugfs to mode 0700.  If the user has
    no access to debugfs, then they won't be able to communicate with the
    systemtap module.  Thus, this should be a non-starter, before even
    loading the module at all.
    
    This was previously causing staprun to fail after loading the module,
    when it checked R/W access to the module's .ctl file.  But since we also
    restrict removing modules to those you can control, staprun would not
    unload the new module either.
