In a buffer with emacs-lisp-mode active, 'define-error' is not fontified
by font-lock mode.  The keyword should be listed somewhere around line 360 in
emacs-lisp/lisp-mode.el.

Recipe:

- Start emacs
- Visit a file ending in .el
- Type: (define-error 'new-error "this is a new error")
- Wait for fontification to complete and notice it is not highlighted

In lisp-mode.el, there is a comment about constructs being updated
automatically from obarray, but I was not able to understand how this
happens, and thought maybe the comment is referring to symbols created
with those commands?

Also bump up test coverage for keywords to ensure they are fontified.
