the fallback to the original default was failing because
it was assuming rhost was already set, so it would always
go back to the first default target. now the auto_target? method
only returns true if can pull an auto_target_host
if the module authour added an automatic target
we skip our routine, to let the module's own automatic targeting
take over as it likely be better

targets now filtered by OS name, but a little
more processing may be needed on this part because
it looks like what you'd expect in os_flavor gets jammed
into name instead
