Subject: ds-identify: recognize container-other as a container, test SmartOS.

In playing with a SmartOS container I found that ds-identify did
not identify the container there as a container.  Systemd-detect-virt
identifies it as 'container-other'.

Also here are tests for ds-identify for the SmartOS platform
identification, and some indentation fixes in ds-identify.
