dist: Support SmartOS

This only includes the basic setup for now. Still need to work on build

LGTM

Another minor thing: Since path doesn't seem to be provided through /etc/profilewe might want to add it as a envvar in the manifest (otherwise jenkins won't find path to git). For now, I've changed tooling path through jenkins admin.

Edit: tooling path nor env injection seemed to work. We'll going to have to edit the manifest. Suggesting adding this:

<envvar name='PATH' value='/usr/local/sbin:/usr/local/bin:/opt/local/sbin:/opt/local/bin:/usr/sbin:/usr/bin:/sbin' />

(btw, confirmed that adding path fixed Jenkins)

Closing in favor of #64
