bug#35022: 26.1; Load order of custom-autoload, custom-load-symbol, custom-loads is backward?

[Allen Li <darkfeline@felesatra.moe>]

Please ignore my patch.  In my haste, I missed that custom-load-symbol
already checks whether a dependency is already loaded, because that
logic wasn't firing for my case (where the load path is an actual path
rather than a package name).

To clarify, the existing code works for this:

;; Called from site-start
(custom-autoload 'foo-some-variable "foo" nil)
;; Called from init.el/package-initialize
(custom-autoload 'foo-some-variable "foo" nil)

But not for this:

;; Called from site-start
(custom-autoload 'foo-some-variable "some/path/to/foo" nil)
;; Called from init.el/package-initialize
(custom-autoload 'foo-some-variable "foo" nil)

I'm not sure yet what the proper approach for my problem is.
