bug#61521: "default" is now the first item returned from (font-faces), breaking various code.

[Brennan Vincent]

Various code seems to expect "default" to be the /last/ item in the list
returned by that function, not the first. For example, this comment in faces.el:

  ;; The `reverse' is so that `default' goes first.
  (dolist (face (nreverse (face-list)))


Also, org-html-htmlize-generate-css does not work when default comes first in
the list (as it skips processing all fonts after default).

I am not sure why this was changed and if the change was intentional, but it can
be fixed by changing the "<" to a ">" in the last line of face-list, so I
suspect it might have been a mistake.
