The patch makes it even worse with two failures now:

F files-tests-file-name-non-special-directory-files-and-attributes
    (void-variable attr-nospecial)

F files-tests-file-name-non-special-file-attributes
    (void-variable attr-nospecial)

I tried changing the new function to:

    (defun files-tests-file-attributes-equal (attr1 attr2)
      ;; Element 4 is access time, which may be changed by the act of
      ;; checking the attributes.
      (setf (nth 4 attr1) nil)
      (setf (nth 4 attr2) nil)
      ;; Element 9 is unspecified.
      (setf (nth 9 attr1) nil)
      (setf (nth 9 attr2) nil)
      (equal attr1 attr2))

Which fixes one but still causes the other to fail:

F files-tests-file-name-non-special-directory-files-and-attributes
    (wrong-type-argument consp nil)
