want same default metrics on SmartOS as on Ubuntu

[bixu]

We are about a 50:50 ratio of SmartOS/Ubuntu, so would love basic metrics for SmartOS as well for use with Leo auto-registration.

What is missing here on SmartOS? There are various Illumos checks, as well as one SmartOS specific one.

IIRC choosing default settings during the interactive Leo setup causes a failure and exit due to Leo expecting nad modules with the same names as those present on Linuxes
