    Let eglot-flymake-backend be in flymake-d-functions even if Eglot off
    
    This is useful when using  eglot-stay-out-of and a pattern like:
    
       (defun my/js-mode-hook ()
         (add-hook 'flymake-diagnostic-functions 'some-eslint-backend nil t))
         (setq-local eglot-stay-out-of '(flymake))
         (add-hook 'flymake-diagnostic-functions 'eglot-flymake-backend nil t))
    
       (add-hook 'js-mode-hook 'my/js-mode-hook)
    
    Then, _both_ backends will run unconditionally, but Eglot backend only
    actually reports diagnostics if Eglot is on.
    
    * eglot.el (eglot-flymake-backend): If buffer isn't being managed
    by Eglot, behave as a noop.
