[PATCH] Use special-mode in eww list modes

[Mark Oteiza]

* lisp/net/eww.el (eww-bookmark-mode, eww-history-mode)
(eww-buffers-mode): Derive from special-mode and remove redundant
setting of buffer-read-only.
(eww-mode-map): Remove redundant keymap parent setting.
(eww-bookmark-mode-map, eww-history-mode-map, eww-buffers-mode-map):
Remove redundant keymap suppressions and mappings.
---

Alternatively, I think it would make sense to use tabulated-list-mode
for these listing buffers, except the bookmark mode, since there is
fancy stuff in there for manipulating bookmarks.
