emacs: restore ns-antialias-text functionality.

This was broken in the Emacs 24.4 release, reported upstream here:
http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg00813.html

Previously, either of the following would disable antialiased fonts
on OS X:

(setq ns-antialias-text nil)

Or:

(setq ns-use-native-fullscreen nil)

While calling those now does not trigger an error, the setting
is no longer respected.  This patch restores that.
emacs: update 24.4 bottle.

Closes #33520.
