org-agenda: Fix the display of more key substitutions

* lisp/org-agenda.el (org-todo-list):
(org-tags-view): Specify the keymap for the substitute-command-keys
call because, as of b6c5a174d, this call is made outside of the agenda
buffer.

The substitute-command-keys call in org-search-view is already taken
care of by 48f333805.
