Subject: SmartOS: Add support for Joyent LX-Brand Zones (LP: #1540965)

LX-brand zones on Joyent's SmartOS use a different metadata source
(socket file) than the KVM-based SmartOS virtualization (serial port).
This patch adds support for recognizing the different flavors of
virtualization on SmartOS and setting up a metadata source file object.
After the file object is created, the rest of the code for the datasource
