Log:
  lualoader: improve drawer error handling
  
  At least one user has landed in a scenario where logo files appear to be
  misnamed, and we failed to find them. Our fallback for missing logodefs is
  orb/orbbw, based on the color status. In a scenario where we can't locate
  the logos, though, this is not ideal. Add in one more layer of fallback
  to properly just don't draw any logo if the fan has been jam packed with
  foreign material.
