fix(wpcarro/emacs): Support OSX build of Emacs r/5291
**TL;DR:**
Most of these changes predicate behavior on the platform:
- At buildtime this is `localSystem == $something`. (`localSystem` is from
  `readTree`)
- At runtime this is `(memq window-system '(ns))`.
- Add `coreutils` so `dired` listing with `--group-directories-first` works
  because that flag depends on the GNU version of `ls`.

**Background:**
I need to support a bunch of OSX users at $WORK. As such, I'm planning
on using my MBP for the next few weeks to build empathy for our
userbase and polish some currently rough edges.

If I'm going to get an serious work done, I need my Emacs setup. Step
one is making sure it can build and run.
